Mont Blanc Goûter Route Conditions 2026: Grand Couloir Status, Refuge Reservations, May Closure & What to Expect This Season
Everything you need to know about climbing Mont Blanc via the Goûter Route in the 2026 season. Refuge du Goûter opens May 30. Tête Rousse Refuge opens May 29. A 2-day Normal Route closure is confirmed for the second half of May for old refuge dismantling preparation. Current Grand Couloir status, crampon requirements, gear lists, and recent trip reports.
If you’re planning to climb Mont Blanc via the Goûter Route this season, several specific things have changed for 2026. The Refuge du Goûter opens May 30 and the Tête Rousse Refuge opens May 29 — both confirmed by the FFCAM. A 2-day closure of the Normal Route is scheduled in the second half of May for preliminary ice and rock-purge operations in the Grand Couloir. This work prepares for the dismantling of the old 1960s Goûter refuge (June 1 through August 15). Reservations at both refuges are mandatory and sell out fast. This page covers all of it, with information verified against the Haute-Savoie prefecture, FFCAM, Chamoniarde mountain conditions service, and recent climber reports.
The 2026 Mont Blanc Goûter Route season runs from approximately May 29 (Tête Rousse opening) through October 4 (Goûter Refuge closing). The peak window is mid-June through early September, when weather is most stable and the route is in optimal condition. Climbers planning ascents in late May should consult the prefecture for the confirmed 2-day closure dates, as exact dates will be announced just a few days before based on weather. The dismantling work itself (June 1 to August 15) does not close the route — climbing continues normally during the construction.
The Grand Couloir remains the single most dangerous section of the route. French mountain police records document 347 rescue operations, 102 deaths, and 230 injuries in the couloir between 1990 and 2017. Hot summer conditions sharply increase rockfall — the Goûter Hut was temporarily closed in 2015 by prefectural order during the heatwave. The 2020 Petzl Foundation study confirmed there’s no safer alternative path. The current protocol is to cross the couloir before 06:00 in the early morning, when rock temperatures are coldest and rockfall is minimal.
Goûter Route Live Conditions Snapshot
Here’s the current status of the Mont Blanc Goûter Route as of May 24, 2026, verified against FFCAM, the Haute-Savoie prefecture, and the Chamoniarde mountain conditions service.
2026 Season Status — Updated May 24, 2026
The May closure matters for your booking. If you’re planning a late May 2026 ascent, the 2-day Normal Route closure could fall on your dates. The Haute-Savoie prefecture will announce exact dates only a few days before the closure based on weather conditions. The Prefect of Haute-Savoie has formally advised climbers to either postpone late-May ascents or use an alternative route (Trois Monts via Cosmiques Hut). Check the FFCAM booking portal and the Chamoniarde mountain conditions service before your scheduled climb dates.
Goûter Route Location & Live Weather
The Goûter Route ascends Mont Blanc from the Saint-Gervais side via the Tête Rousse and Goûter refuges. The approach starts at the Tramway du Mont-Blanc from Saint-Gervais, which deposits climbers at the Nid d’Aigle station (2,372 m). From there, climbers hike on foot to Tête Rousse Refuge (3,167 m). The route then crosses the Grand Couloir and ascends the Aiguille du Goûter scramble to the Goûter Refuge (3,835 m). The final ascent follows the Bosses Ridge to the summit. Mont Blanc summit coordinates: 45.8326°N, 6.8642°E.
Live weather data from Open-Meteo at Goûter Refuge coordinates (3,835m). Summit temperatures at 4,808.7m typically run 5-8°C colder than the refuge with significantly higher wind. Always check Météo-France high-altitude forecasts and the Chamoniarde mountain conditions service before your summit day.

The 2026 2-Day Route Closure: What You Need to Know
On April 7, 2026, the Haute-Savoie prefecture issued a press release announcing a confirmed closure of the Normal Route in the second half of May 2026. This is the most consequential operational change for the 2026 season, and any climber with a late-May reservation needs to understand what it means.
Why the Closure Is Happening
The closure is preparatory work for the dismantling of the old Goûter refuge — the 1960s building at 3,817 m that has been closed since 2013. Before the dismantling itself can begin in June, the Haute-Savoie prefecture requires ice and rock-purge operations in the Grand Couloir. These purges deliberately trigger rockfall and ice release to clear unstable material from the route. The work creates serious rockfall hazard during the operation, which is why the route closes entirely for those two days.
When Exactly Will the Route Close?
The prefecture has confirmed the closure will happen in the second half of May 2026, but exact dates depend on weather. The prefect’s announcement states that dates will be communicated only a few days before the operation. Climbers planning ascents between May 16 and May 31 should monitor the Haute-Savoie prefecture website and the FFCAM booking portal for updates.
What’s Closed and What’s Open
- Closed: The route between Tête Rousse Refuge and the Refuge du Goûter (the Grand Couloir traverse section)
- Closed: Winter (unguarded) shelters at both refuges during the entire second half of May 2026
- Open: The Refuge du Goûter from May 30 onwards (after the closure window)
- Open: The Tête Rousse Refuge from May 29 onwards (after the closure window)
- Open: The Trois Monts route via Cosmiques Hut (alternative)
- Open: All other Chamonix valley climbing routes
How the Closure Is Enforced
The prefecture has confirmed that gendarmes will be present at both the Tête Rousse and Goûter refuges during the closure period. Climbers attempting to ascend during the closure will be turned back. The closure applies regardless of whether you have a guide, regardless of your prior summits, and regardless of weather. This is not a guideline — it’s a legal restriction.
Prefect’s official advisory. Emmanuelle Dubée, the prefect of Haute-Savoie, has formally invited climbers planning Mont Blanc ascents during the second half of May 2026 to either postpone their project or take an alternative route. This applies to both the ascent and descent. The Trois Monts route via the Cosmiques Hut is the standard alternative during the closure period.
The Grand Couloir: Why It’s the Most Dangerous Section
The Grand Couloir is a 3,340-meter gully on the Aiguille du Goûter that climbers must cross on foot to reach the scramble between Tête Rousse and the Goûter refuge. Despite being only about 30 meters wide, this single section accounts for the majority of fatalities on the Mont Blanc Goûter Route.
The Numbers
French mountain police records document the following statistics for the Grand Couloir:
- 1990-2011: 291 rescue operations, 74 deaths, 180 injuries
- 1990-2017 (cumulative): 347 rescue operations, 102 deaths, 230 injuries
- Average: Roughly 4-5 deaths per year over a 27-year period
These numbers come from French gendarmerie de haute montagne records and are the most reliable data available on Alpine climbing fatality statistics. The actual count is likely higher when near-misses and minor injuries are included.
Why Rockfall Is the Hazard
The Grand Couloir channels falling rocks from the upper Aiguille du Goûter face. When the rock is bound together by ice and snow (cold conditions), rockfall is minimal. When temperatures rise and the ice melts, surface rocks become loose and the couloir becomes a natural rockfall funnel. The 2003 European heatwave saw a dramatic spike in Grand Couloir accidents. The 2015 summer was so dangerous that the Goûter Hut was temporarily closed by prefectural order to dissuade climbers from attempting the route.
The Modern Crossing Protocol
Guided parties cross the Grand Couloir before sunrise, typically between 03:00 and 05:00. At this hour, rock temperatures are coldest, ice is most consolidated, and rockfall is at its statistical minimum. The crossing itself takes 2-5 minutes for an experienced team moving efficiently. The protocol is:
- Approach the couloir from Tête Rousse side
- Wait for the team ahead to be fully across before starting
- Move continuously — no stopping in the couloir
- Helmets mandatory; keep looking up
- If you hear rockfall, drop and shelter against the safer side of the gully
The 2020 alternative route study. The Petzl Foundation funded a 2020 study exploring whether an alternative path could replace the Grand Couloir crossing. The study concluded that any alternative route would be more dangerous than the current path. The Grand Couloir remains the route — there is no safer way around it. This is why early-morning crossing discipline matters so much.
The 2026 Camp Progression: Nid d’Aigle to Summit
The standard 3-day program for the Mont Blanc Goûter Route uses a deliberate progression. The schedule allows acclimatization, breaks the Grand Couloir crossing into the safest hours, and positions the summit attempt for optimal conditions. Here’s the camp-by-camp breakdown.
Day 1: Saint-Gervais → Nid d’Aigle → Tête Rousse Refuge (3,167 m)
Most climbers start in Chamonix or Saint-Gervais. Take the Tramway du Mont-Blanc from Saint-Gervais up to the Nid d’Aigle station at 2,372 m. From there, follow the well-marked trail uphill to the Tête Rousse Refuge at 3,167 m. The hike covers about 800 meters of elevation gain in approximately 3-4 hours.
The Tête Rousse Refuge sleeps 72 in summer plus 16 in winter, with 50 tent spots in the adjacent base camp area (reservation required for tents). Most climbers stay one night here for acclimatization before continuing to the Goûter the following morning. Some choose to stay 2 nights at Tête Rousse instead of moving to the Goûter. The trade-off is an extra 2-3 hours on summit day. The benefit is avoiding the most crowded refuge and reducing Grand Couloir exposure to a single crossing.
Day 2: Tête Rousse → Grand Couloir → Goûter Refuge (3,835 m)
This is the technical day. Depart Tête Rousse at first light to cross the Grand Couloir before the sun hits the upper rock faces. The traverse itself takes 2-5 minutes. Above the couloir, the route climbs a 600-meter scramble up the Aiguille du Goûter — exposed Class 3-4 terrain with some fixed rope sections in the steeper bits. Total time from Tête Rousse to the Goûter Refuge is 3-5 hours depending on conditions and team speed.
The Refuge du Goûter at 3,835 m is the highest staffed mountain hut in France. The ovoid-shaped 2013 building sleeps 120 in dormitories. Its stainless steel cladding is rated for wind speeds up to 300 km/h. Climbers typically arrive by mid-morning, eat lunch, rest in the afternoon, and have an early dinner before sleeping for 5-6 hours ahead of the summit day. The atmosphere in the refuge is particularly intense — most climbers are mentally preparing for the next morning’s ascent.
Day 3: Goûter → Bosses Ridge → Summit (4,808.7 m) → Descent
Summit day starts between 02:00 and 03:00 depending on group size and conditions. Headlamps on, climbers depart the Goûter Refuge for the Bosses Ridge — the long snow-and-ice ridge that runs from the refuge to the summit. The route climbs the Dôme du Goûter (4,304 m), then follows a corniced ridge to the Vallot bivouac shelter (4,362 m, emergency only). From there it continues up the Bosses Ridge to the summit.
Total summit day from the Goûter Refuge is typically 8-12 hours round trip: 5-7 hours to the summit, 3-5 hours back to the refuge. From the refuge, most climbers descend the same day all the way back to Tête Rousse and onward to Nid d’Aigle. That makes it a long day with significant total elevation loss — about 2,400 meters from summit to Nid d’Aigle.
Are Crampons Necessary on the Mont Blanc Goûter Route Right Now?
Yes. Crampons are required equipment on the Mont Blanc Goûter Route for the entire 2026 season. The question is when you put them on — and that varies meaningfully by season window.
Late May – Mid-June 2026 (Early Season)
Early-season climbers find more snow on the route than mid-season climbers. The upper Aiguille du Goûter scramble can have residual snow patches that warrant crampons earlier than peak-season climbers experience. The Bosses Ridge above the Goûter Refuge is consistently snow-covered.
Early-season protocol: Carry crampons from Tête Rousse. Be ready to put them on partway up the Aiguille du Goûter if snow patches persist. Use them continuously from the Goûter Refuge to the summit. The descent is often faster but still requires crampons through the Bosses Ridge.
Mid-June – Early September 2026 (Peak Season)
Peak season offers the driest rock on the lower route. Most climbers won’t need crampons below the Goûter Refuge. The standard transition point is at or just above the refuge, where the route enters the Bosses Ridge for the final ascent to the summit.
Peak-season protocol: Carry crampons from Tête Rousse. Put them on at or just above the Goûter Refuge. Keep them on continuously through the Bosses Ridge to the summit and back. The Vallot Hut to summit section consistently requires crampons.
Mid-September – October 4, 2026 (Late Season)
Late-season conditions vary year to year. The lower route is typically dry, but autumn cold fronts can deposit fresh snow on the upper Bosses Ridge between climbing days. Watch the Chamoniarde mountain conditions service for current snow line data.
Late-season protocol: Always carry crampons. Use them above the Goûter Refuge by default. Check overnight forecasts — autumn snow events can shift the snow line significantly.
Crampons aren’t optional even on dry days. Multiple Mont Blanc fatalities involve climbers who left crampons at the refuge because the route looked dry on the ascent. The Bosses Ridge is consistently snowy and icy regardless of how the lower mountain looks. Always have crampons, ice axe, and helmet with you on every summit attempt. The descent is not the same surface as the ascent.
Month-by-Month 2026 Conditions: What to Expect
| Month | Refuge Status | Route Conditions | Crowds | Best/Worst For |
|---|---|---|---|---|
| Late May | Tête Rousse opens May 29; Goûter opens May 30 | Snowier upper route; 2-day closure for purges | Minimal | Best: cooler, less crowded. Worst: 2-day closure, partial refuge access. |
| June | Both refuges open; dismantling work begins June 1 | Stabilizing; consolidated snow | Building | Best: fresh ice, fewer crowds. Worst: weather variability. |
| July | Both refuges fully operational | Best route conditions; Grand Couloir crossings managed | Maximum | Best: most reliable weather. Worst: crowded refuges, queue at Grand Couloir. |
| August | Both refuges fully operational; dismantling continues through Aug 15 | Warm; rockfall risk peaks; afternoon thunderstorms | Maximum | Best: warmest temps. Worst: peak rockfall season, congestion. |
| September | Both refuges open; thinning crowds | Cooler nights; route consolidates again | Reducing | Best: less crowded, decent weather. Worst: variable autumn fronts. |
| Early October | Goûter closes Oct 4 (07:00); Tête Rousse Oct 3 | Season closing; cold conditions | Minimal | Best: empty refuges. Worst: season closing, infrastructure reducing. |
July 2026: Peak Season Sweet Spot
July is statistically the most reliable month for Mont Blanc summits. Weather windows open every 3-5 days, the Grand Couloir crossings are managed by guide services with clear protocols, and the route is in optimal condition. The trade-off is maximum refuge crowding — Refuge du Goûter is at 120-person capacity on virtually every July night, and reservations released in April 2026 sold out within hours. Climbers booking in July typically need to either work through a guide service (which has block reservations) or grab last-minute cancellations.
August 2026: Rockfall Risk Peaks
August brings the warmest temperatures of the year, which means peak rockfall risk in the Grand Couloir. Hot days like those in summer 2003 and 2015 trigger far more rockfall events than cooler periods. Some guide services have shifted August departures to earlier 02:00 starts (instead of 03:00) to ensure the Grand Couloir crossing happens before any sun hits the upper rock face. Climbers booking August trips should expect this earlier departure pattern.
September 2026: Quieter Late Season
September brings reduced crowds, cooler temperatures, and a quieter overall experience. Weather remains generally favorable through mid-month before autumn fronts increase risk. The Refuge du Goûter remains at capacity for the first two weeks but loosens up by late September. Climbers willing to accept slightly more weather risk often find September preferable to August for the lower crowds alone.
Recent Mont Blanc Trip Reports (2025 Season Synthesis)
The 2025 Mont Blanc season produced over 25,000 ascent attempts via the Goûter Route, with mixed results across the season. Here’s a synthesis of patterns from climber reports, guide service summaries, and Chamoniarde data.
2025 Season Summary
The 2025 season ran from late May through early October following standard FFCAM dates. The Refuge du Goûter operated at near-capacity throughout July and August. Grand Couloir rockfall events were elevated during the late-July heat wave, with three documented serious incidents requiring helicopter evacuation. The 03:00 standard departure was strictly enforced by all major guide services during the hot weather window.
2025 Refuge Reservation Patterns
The 2025 booking experience set the precedent for 2026: reservations opened in early April, with prime July dates selling out within hours. Independent climbers without guide service reservations reported significant difficulty securing both Tête Rousse and Goûter dates for the same trip. Guide services with block bookings had advantage. The Compagnie des Guides de Saint-Gervais (which has guided the Goûter Route since 1864) reported their full 2025 season was booked by mid-February.
2025 Climber Notes from Trip Reports
Independent climbers on SummitPost, UKClimbing, and trip-report sites shared several common 2025 observations relevant to 2026 planning:
- Tramway du Mont-Blanc timing: Last departure from Nid d’Aigle is approximately 17:30 in summer. Plan descent to make this train or face overnight at refuge.
- Refuge food quality: Mostly positive. €85-€110 half-board reflects French alpine pricing. The €10 mandatory bag sheet is sold at the refuge.
- Grand Couloir queues: July-August saw queues of 20-40 climbers waiting to cross the couloir at peak hours. Crossings happen in pulses to minimize exposure time per climber.
- Vallot Hut overnighting: Officially emergency only, but used by some climbers as planned bivouac in fast-and-light style. Guide services discourage this — only use for genuine emergencies.
- Cell signal: Variable above Tête Rousse. Goûter Refuge has wifi during operating season. The summit and Bosses Ridge generally have no signal.
- Helicopter rescue: PGHM (Peloton de Gendarmerie de Haute Montagne) operates from Chamonix. Rescues are typically free for emergencies in France, but travel insurance with mountain rescue coverage is strongly recommended.
2026 Operational Changes
For 2026, the dismantling of the old Goûter refuge represents the only major operational change to the route. The new Refuge du Goûter (the modern ovoid building) continues to operate normally. The Tête Rousse Refuge continues to operate normally. The Trois Monts alternative route remains available for climbers affected by the May closure.
Required Gear for the 2026 Mont Blanc Goûter Route

2026 Booking Strategy
Reservations at the Tête Rousse and Goûter refuges are mandatory and competitive. The FFCAM booking portal opened in early April 2026 and prime July-August dates sold out within hours. Here’s how to approach booking for the rest of the 2026 season and for 2027.
For Remaining 2026 Dates (Late May – Early October)
If you haven’t booked yet for 2026, your options are limited. Check the FFCAM portal regularly for cancellations — they do happen, particularly 1-2 weeks before climb dates as climbers reassess weather. Late September dates are typically still available even in May for booking. Guide services often have block reservations they can release to clients on shorter notice.
For 2027 Booking
The 2027 booking window will open in approximately April 2027 on the FFCAM portal. Climbers planning 2027 summits should:
- Set calendar reminders for early April 2027 to monitor the FFCAM portal
- Have backup dates ready (the system fills in real time)
- Consider booking through a guide service like the Compagnie des Guides de Chamonix, which has block reservations
- Avoid resale markets — FFCAM prohibits reservation resales and verification at the refuge will turn you away if the reservation is in someone else’s name
Guide Service Booking
Standard 3-day Mont Blanc programs from Chamonix-based guide services run €1,400-€3,500 EUR per climber depending on operator and group size. The Compagnie des Guides de Chamonix (founded 1821, the oldest mountain guide company in the world) and the Compagnie des Guides de Saint-Gervais are the standard choices. Both have block reservations at the refuges and handle the FFCAM booking on behalf of their clients.
Frequently Asked Questions About Mont Blanc Goûter Route Conditions
When does the Mont Blanc Goûter Route 2026 season open?
The Refuge du Goûter (3,835 m) opens to the public on May 30, 2026 and closes on October 4, 2026 at 7 a.m. The Tête Rousse Refuge (3,167 m) opens earlier on May 29, 2026 and closes on October 3, 2026 at 7 a.m. These dates are set by the FFCAM. The Normal Route via the Goûter is climbable from late May through early October, with peak conditions running from mid-June through early September. Reservations at both refuges are mandatory and frequently sell out for prime dates within hours of becoming available.
Will the Mont Blanc Normal Route be closed in 2026?
Yes. The Normal Route via the Goûter will be closed for two days during the second half of May 2026. The Haute-Savoie prefecture confirmed on April 7, 2026 that the dismantling of the old Goûter refuge requires preliminary ice and rock-purge operations in the Grand Couloir. Gendarmes will enforce the closure at both Tête Rousse and Goûter refuges. The exact dates will be confirmed a few days before the operation based on weather conditions. The dismantling work itself runs June 1 through August 15, 2026 but does not close the Normal Route — climbing continues normally during the construction.
How dangerous is the Grand Couloir on the Mont Blanc Goûter Route?
The Grand Couloir is the most dangerous single section of the Mont Blanc Goûter Route and one of the deadliest places in Alpine mountaineering. French mountain police records show 347 rescue operations, 102 deaths, and 230 injuries in the couloir between 1990 and 2017. The 3,340-meter altitude gully must be traversed on foot. Rockfall is the primary hazard, with the risk highest in dry conditions when minimal snow binds the loose surface rocks. Modern guided protocol is to cross the couloir before 06:00 in the early morning, when temperatures are coldest and rockfall is at its statistical minimum.
Do I need crampons on the Mont Blanc Goûter Route right now?
Yes. Crampons are required on the Mont Blanc Goûter Route for the entire 2026 season. The standard transition point is above the Goûter Refuge at 3,835 m, where the route enters the Bosses Ridge for the final ascent. Early-season climbers (late May through mid-June) may need crampons earlier on the route. Late-season climbers (September) typically find the lower mountain dry but still need crampons from the Goûter onwards. The Bosses Ridge is consistently snowy and icy throughout the season.
How much does it cost to climb Mont Blanc via the Goûter Route in 2026?
A guided Mont Blanc Goûter Route climb in 2026 typically costs €1,400-€3,500 EUR per climber. Standard 3-day programs from Chamonix with an IFMGA guide run €1,500-€2,000 per person. Premium private guiding runs €2,500-€3,500. Refuge costs add €85-€110 per night for half-board, totaling €170-€220 for the two-night stay. The Tramway du Mont-Blanc round trip costs approximately €40-€50. Mandatory bag sheet at the refuges costs €10. Total trip budget including international flights to Geneva or Lyon typically runs €2,500-€5,000 EUR per climber.
How long does it take to climb Mont Blanc?
The standard guided Mont Blanc Goûter Route program runs 3 days from Chamonix or Saint-Gervais. Day 1 covers the approach via Tramway du Mont-Blanc and the hike to the Tête Rousse Refuge. Day 2 ascends through the Grand Couloir and up the Aiguille du Goûter scramble to the Goûter Refuge. Day 3 is summit day from the Goûter via the Bosses Ridge to the summit and back to Chamonix. Some climbers add a fourth day for acclimatization or weather buffer. Fast experienced parties can do single-push ascents in 12-18 hours from Tête Rousse, but this is not recommended for first-time Mont Blanc climbers.
Can I camp or bivouac on the Mont Blanc Goûter Route?
No. Camping and bivouac are banned in the entire classified Mont-Blanc site by ministerial decree. The only exception is the Tête Rousse base camp area, which allows 50 tent spots — reservations required through the FFCAM portal, same as the refuge. The Vallot bivouac shelter at 4,362 m is emergency only and cannot be planned as overnight accommodation. The ban is actively enforced; climbers caught bivouacking outside designated areas face fines and may be turned away from refuges.
What fitness is required for the Mont Blanc Goûter Route?
The Mont Blanc Goûter Route requires solid mountain fitness but not elite-level cardio. Standard benchmarks: hike 4-6 hours per day with 250-400 vertical meters per hour for multiple consecutive days. Summit day from the Goûter Refuge covers approximately 1,000 m of vertical gain over 5-7 hours of climbing — a sustained 150-200 m/h pace at altitude. Climbers should have prior 3,000m+ experience and be comfortable using crampons and ice axes on moderate terrain. The route is graded PD+ to AD- in the Alpine grading system. Guide services typically require fitness verification via a test climb on a smaller peak before accepting clients for Mont Blanc.
What is the Refuge du Goûter like?
The Refuge du Goûter at 3,835 m is the highest staffed mountain hut in France. The current ovoid-shaped building was completed in 2013 and replaced the old 1960s refuge that is being dismantled in 2026. It sleeps 120 climbers in dormitories across four floors, with a stainless steel exterior cladding designed to withstand winds up to 300 km/h. Reservations are mandatory through the FFCAM portal. Half-board (dinner, bed, breakfast) costs €85-€110 per night. The €10 bag sheet is mandatory and sold at the refuge if you don’t bring one. Crocs are provided as hut shoes. The atmosphere is intense — most climbers are mentally preparing for the next morning’s summit attempt.
Should I climb Mont Blanc by the Goûter Route or the Trois Monts?
The Goûter Route handles roughly 80% of Mont Blanc ascents and is the standard choice for first-time climbers. It’s more straightforward, has more established refuge infrastructure, and the Compagnie des Guides has been guiding the route since 1864. The Trois Monts route (via Cosmiques Hut and the Aiguille du Midi cable car) is more technical. It involves the Tacul and Mont Maudit traverses. The trade-off is that it avoids the Grand Couloir rockfall hazard entirely. Most climbers choose the Goûter for their first attempt. The Trois Monts becomes the standard alternative during 2026 closure periods (the 2-day late-May closure) or for climbers seeking less crowded terrain.
