Longs Peak Gear List 2026: Complete Keyhole Route Checklist

The standard Keyhole Route does not call for technical climbing gear under dry summer conditions, but the combination of length, exposure, weather, and altitude means it rewards the same gear discipline as a harder objective. The four Class 3 sections, the Ledges, the Trough, the Narrows, and the Homestretch, are sustained scrambling on exposed terrain where a fall is often fatal, so footing, weather judgment, and route-finding all matter as much as the packing list. The single most important item is the one people are tempted to leave behind.

The route runs trailhead (9,400 ft) to the Chasm Lake junction (~10,000 ft), Granite Pass (~12,000 ft), the Boulderfield camp (12,760 ft), the Keyhole notch (13,160 ft), then the Ledges, the Trough, the Narrows, and the Homestretch to the summit at 14,259 ft. Here is the required Keyhole kit:

• UIAA climbing helmet – mandatory above the Keyhole (Petzl Sirocco, Black Diamond Capitan)
• Headlamp plus spare batteries – a primary plus backup; lithium cells hold up in cold (Petzl Actik Core 450, Black Diamond Spot 400)
• Trekking poles – collapsible carbon or aluminum; a huge help on the long descent (Black Diamond Distance Carbon Z, Leki Cross Trail)
• Day pack 25-35 L – with compression straps and pole attachment (Osprey Talon 33, Black Diamond Distance 22)
• Water 3-4 L – a 3 L bladder plus a 1 L insulated bottle
• Trail runners or approach shoes – sticky rubber for the Class 3 rock (La Sportiva TX4, Five Ten Guide Tennie)
• Layering system – base, mid, hardshell, warm hat, light gloves, and a puffy for breaks
• Sun protection – SPF 50+, lip balm, category 3-4 sunglasses, sun hat
• Navigation – map, compass, and a GPS app with offline maps (Gaia GPS, CalTopo)
• Food – 1,000-1,500 calories: bars, trail mix, a sandwich, salt tablets
• First aid – tape, ibuprofen, blister treatment, antiseptic wipes
• Emergency communication – a satellite messenger; cell coverage is unreliable above the Boulderfield (Garmin inReach Mini)
• Microspikes – seasonal, for early and late-season snow patches (Kahtoola MICROspikes)

Water is one of the most common things climbers get wrong on Longs, so it earns its own section. The lower, forested miles of the trail cross running water, including Alpine Brook early on, so you can start with less and top up before treeline if you carry a filter. Above the Chasm Lake junction and Granite Pass, reliable sources disappear for the rest of the climb; the exception is the creek at the Boulderfield (12,760 ft), which campers and some day climbers use to refill on the way down. Treat everything, since giardia is a real risk. In practice, most day climbers carry the full 3 to 4 litres from the trailhead, because stopping to filter on a timed race against afternoon storms rarely pays off. Carry a filter or drops as a backup, insulate at least one bottle for cold starts and shoulder-season freezes, and drink steadily; dehydration at altitude quietly worsens both fatigue and altitude sickness.

Cables Route (Class 4, north face)

The historic Class 4 line up the north face, named for the steel cables installed in 1925 and removed in 1973. It is shorter on the upper mountain than the Keyhole but more exposed, and it is climbed by confident scramblers. Some parties protect the Class 4 with a short rope. Additions beyond the Keyhole kit:

• 30 m short rope – optional protection for the Class 4 (single 9.5 mm dynamic)
• Light rack – optional 2-4 small to medium cams (.4 to 1) if running rope
• Harness + belay/rappel device – lightweight alpine harness and an ATC with autoblock for descent
• 2-3 locking carabiners, slings, cordelette – if building anchors

Loft Route (Class 3-4 via the Loft saddle)

Ascends via the saddle between Longs and Mount Meeker from Chasm Lake, using Clark’s Arrow as a key route-finding feature. It works as an alternate ascent, a descent after the Keyhole or Diamond, or part of a Longs-Meeker link-up. Route-finding is more committing than the Keyhole. Additions:

• Detailed route description or GPX track – 14ers.com or Roach’s Colorado Fourteeners
• Extra water, 4-5 L – the Loft is longer than the standard Keyhole
• Optional short rope – for Class 4 sections if used
• Confidence on sustained Class 3-4 exposure – prior Colorado experience helps

The Diamond, Casual Route (5.10a Grade IV)

The easiest big-wall line on Longs’ east face: 5.10a, Grade IV, seven pitches, ~900 ft of vertical. This is a serious alpine rock climb for experienced parties with prior 5.10 alpine experience and acclimatization to 14,000+ ft. Full technical kit:

• 60 m single dynamic rope (some carry 70 m), full alpine rock rack (cams .3 to 3, wired nuts, small cams for granite seams)
• Harness, belay/rappel device, 6-8 lockers, 8-10 alpine draws, slings + cordelette
• Rock shoes for the 5.10a and approach shoes for the descent
• UIAA helmet, headlamp + spares, satellite messenger; optional bivy kit for a Broadway ledge start

• Steel 12-point mountaineering crampons – not aluminum (Petzl Vasak, Black Diamond Sabretooth)
• General mountaineering ice axe – 50-65 cm (Black Diamond Raven, Petzl Glacier)
• B2 or B3 mountaineering boots (Scarpa Mont Blanc Pro, La Sportiva Nepal)
• Avalanche safety gear – beacon, probe, shovel, for any snow-loaded slope
• 4-season tent, 0 to -20 F sleeping bag if camping
• Insulated alpine pants, expedition puffy, layered gloves and mittens, goggles
• Insulated bottles (hoses freeze), liquid-fuel stove (MSR XGK), snowshoes or skis for the approach
• Avalanche education – Level 1 minimum recommended

July to September (standard): dry rock, little to no snow above 12,000 ft, reliable afternoon storms, 40 to 65 F at altitude. The standard summer kit above, no crampons or axe in most conditions. June (early): expect snow patches above ~11,000 ft and possible snow in the Trough; add microspikes (often mandatory), a light axe if snow is substantial, warmer base layers, and gaiters, and check 14ers.com first, since early-season attempts fail often on conditions. October to November (late): excellent weather with fewer storms, but shorter days demand earlier starts and headlamp use, colder nights, and readiness for the first winter snowfalls; carry microspikes and warmer layers. December to April (winter): full winter requirements as above; every summer assumption resets.

• Tent – 3-season+ wind-resistant (Big Agnes Copper Spur, MSR Hubba Hubba); 4-season if early/late
• Sleeping bag – 15 F or lower; down for weight, synthetic if wet is likely
• Sleeping pad – R-value 4+ (Therm-a-Rest NeoAir XTherm)
• Bear canister or the provided bear boxes – mandatory at the Boulderfield
• Stove + fuel, 1 L pot, long spoon – one canister per two people per two days
• Water filter or treatment – Sawyer Squeeze, Aquamira, or boiling
• Headlamp + spares, permit copy, wag bag/trowel – pack out human waste above treeline

• No helmet or wrong helmet – rockfall in the Trough is constant; a bike helmet does not count
• Too little water – 2 L on a 14-mile day at altitude invites dehydration and altitude sickness
• Wrong footwear – stiff boots dull your feel on Class 3; mountaineering boots are summer overkill
• Late start – after 4 AM in summer sharply raises lightning exposure
• One headlamp, no spare – a failure in the pre-dawn or post-dusk descent strands you
• Cotton anywhere – base layers, socks, or hats in cotton create hypothermia risk
• No emergency comms – cell coverage above the Boulderfield is unreliable
• Thin layering – storms can drop temps 30 to 40 F in minutes; carry the shell and warm hat regardless of forecast

The priciest single items are the hardshell jacket ($150-$400), the satellite messenger ($300-$400 plus subscription), the day pack ($80-$250), and the helmet ($60-$150). The most under-budgeted item is the pack itself; many climbers attempt Longs with an inadequate one and regret it on the long descent.

You do not need to buy everything to climb Longs, and for a one-time summit or a first winter attempt, renting the costly items is the smart move. Own these, because fit and familiarity matter and you will reuse them: helmet, footwear, day pack, layering system, headlamp, and trekking poles. Rent these, because they are expensive, bulky, or winter-specific: mountaineering boots, crampons, ice axe, a 4-season tent, avalanche safety gear, and a bear canister for a Boulderfield night. REI Co-op rents most of the technical and camping items from its Front Range stores (Denver, Boulder, Fort Collins), and specialty shops such as Neptune Mountaineering in Boulder carry rentals and expert fitting; Estes Park outfitters near the trailhead are handy for last-minute bear-canister rentals. Reserve winter and summer-weekend rentals ahead, since Colorado 14er season strips shelves fast.

Longs sits in the middle of Colorado’s 14er difficulty spread, and its gear list reflects that. On the easy Class 1 to 2 peaks such as Grays and Torreys, Mount Bierstadt, Quandary, and Mount Elbert, a standard hiking kit is enough: no helmet, no scrambling-specific footwear, just layers, water, sun protection, and navigation. Longs (Class 3 Keyhole) adds the helmet, sticky-rubber footwear, larger water capacity, and the alpine-start discipline that the exposure and weather demand. The hard Class 4 peaks, Capitol, the Maroon Bells, Crestone Needle, Pyramid, and Little Bear, push further still, with mandatory helmets, more committing route-finding, and parties often carrying a rope and light rack. If Longs is your first Class 3 14er, it is a real step up from a Bierstadt hike, and a sensible rung below the Elk Range’s Class 4 test-pieces. See our Colorado 14ers guide, best mountains near Denver, and the Longs Peak difficulty and safety guide to place it in context.

Pack out all waste, including human waste above the Boulderfield with a wag bag, and verify current timed-entry rules at nps.gov/romo before you drive up, since they change yearly. Full detail is in our Longs Peak permits and logistics guide.
