Mountain Route Comparisons: choose the right line on 24 major peaks
Every major mountain has more than one way up – and the choice between routes is one of the highest-leverage decisions in expedition planning. Success-rate gaps of 10 to 35 percentage points are common between routes on the same mountain, often bigger than the gap between guided and independent climbing. Each page below breaks down how the routes differ in grade, cost, weather window, permits, and guided availability – and ends with an explicit verdict for beginner, intermediate, and expert climbers.
Route choice drives 10-35 point success gaps – and it’s usually infrastructure, not terrain.
On the same mountain, the “easy” and “hard” routes can differ in summit success by more than the guided-vs-independent gap. But the surprise in the data: most of the spread comes from infrastructure – cable cars, huts, established camps, acclimatization time – not from technical grade. Elbrus North is barely more technical than South, yet sits 13 points lower because it lacks the cable car and hut access.
The single clearest example is Kilimanjaro: the 8-day Lemosho (85%) vs the 5-day Marangu (50%) – a 35-point gap on the same terrain, driven almost entirely by acclimatization time. Book the cheapest 5-day package and you’re unknowingly accepting a 35-point cut in your odds.
Why route choice matters more than most climbers realise
The route-driven spread is comparable to, or larger than, the gap between guided and independent climbing.

Explore Travel Shop on Expedia →Success-rate gaps of 10 to 35 percentage points are common between routes on the same mountain. On Kilimanjaro, the Lemosho 8-day runs 85% while the Marangu 5-day runs 50% – a 35-point gap driven almost entirely by acclimatization time. On Elbrus, the South Route runs 75% vs the North at 62% – a 13-point gap from cable-car access and hut infrastructure. On Mont Blanc, the Goûter runs 65% vs the Cosmiques approach at 53% – a 12-point gap from approach length and hut spacing. The pattern is consistent: on most peaks the success-rate gap reflects infrastructure differences more than terrain technical difficulty, and climbers focused purely on a route’s technical character often overlook the infrastructure advantage that drives most of the spread.
What each comparison page covers
Every page follows the same 8-section structure – so peak-to-peak comparisons stay straightforward.
Quick comparison table
Distance, elevation gain, technical grade, average expedition days, cost difference, and best season – all routes side by side in one scannable table.
Route A deep-dive
Full breakdown of the standard or most popular route: overview, key sections, high-camp profiles, objective hazards, and route-specific gear notes.
Route B deep-dive
The same structure applied to the alternative route. Where mountains have three or more routes (Mont Blanc, K2, the Mexican volcanoes), each line gets its own deep-dive.
Who chooses each route
A decision matrix mapping experience level, schedule, budget, and goals to the route that serves each climber profile best.
Weather windows compared
How the season and summit window differ by route, including route-specific hazards that don’t appear in overall mountain data (e.g. Elbrus North’s wind exposure).
Permit & fee differences
What each route costs beyond the standard permit – hut fees, approach transport, and route-specific logistics like Mont Blanc’s Goûter Hut bookings.
Guided availability per route
Which routes have commercial guide support, which operators run each, and what the guided-to-independent rate gap looks like by route.
Verdict by climber profile
The explicit recommendation for beginner, intermediate, and expert climbers – with the reasoning stated directly. The section the rest of the page builds toward.
The biggest route gaps in mountaineering
The peaks where route choice has the highest impact on your summit probability – usually driven by infrastructure, not terrain.
| Mountain | Routes compared | Success gap | Why |
|---|---|---|---|
| Kilimanjaro | Lemosho 8-day vs Marangu 5-day | 35 points | Acclimatization time – the longer itinerary advantage |
| Denali | West Buttress vs Cassin Ridge | ~25 points | Standard guided route vs expedition-grade technical climbing |
| Elbrus | South Route vs North Route | ~13 points | Cable-car infrastructure on South; full self-carry on North |
| Mont Blanc | Goûter vs Cosmiques (technical) | ~12 points | Approach length; technical grade jump on the Cosmiques traverse |
| Pico de Orizaba | Jamapa Glacier vs Labyrinth | ~12 points | Glacier route safety and consistency vs labyrinth complexity |
| Aconcagua | Normal vs Polish Glacier | ~10 points | Technical demands of glacier ice on Polish vs standard scree |
| Rainier | DC vs Emmons Glacier | ~8 points | Infrastructure and traffic on Disappointment Cleaver vs remote Emmons |
| Everest | South Col vs North Ridge | ~5 points | Roughly equivalent; the real differences are cost and crowding, not success rate |

Success Rates Hub Which Mountain?How the verdict works
Each page ends with a three-tier verdict – stated directly, with the trade-offs shown. It doesn’t always pick the easiest or hardest route.
| Climber profile | Verdict criteria | Typical recommendation |
|---|---|---|
| Beginner First attempt, limited experience | Highest success rate, best infrastructure, most forgiveness for preparation gaps | The standard route (Lemosho on Kilimanjaro, West Buttress on Denali, South on Elbrus, Normal on Aconcagua, Goûter on Mont Blanc) |
| Intermediate Prior alpine experience, specific goals | Balances success rate against experience development and future-applicable skills | Often a moderately harder route that builds skills (Polish Glacier on Aconcagua, West Rib on Denali, Cesen on K2) |
| Expert Technical alpinist, maximum challenge | The line that best uses the expert’s skills – without defaulting to the hardest route for its own sake | Often the most technically interesting line matching the climber’s background (Cassin Ridge on Denali, South Face on Lhotse, technical lines on Mont Blanc) |
The intermediate verdict is where experience-development gets priced in: the highest-success-rate route isn’t always the best choice. Intermediate climbers often benefit more from a moderately harder route that builds skills for future objectives – so each page states what skills the recommended route develops and which future objectives those skills support.
Sources & methodology
Every page cross-references multiple authoritative sources to avoid operator-specific bias.
Primary data sources (13+)
- Argentine Park Service (APN) – Aconcagua permit records and Provincial Park summit registry
- National Park Service (NPS) Denali & Mount Rainier – permit records, ranger summit registries, incident reports
- Tanzania National Parks Authority (TANAPA) – Kilimanjaro permit records 2005-2025 (the largest sample in the dataset)
- Russian Mountain Federation & Elbrus Rescue Service – registration records and incident logs from Terskol
- Compagnie des Guides de Chamonix & OHM – Mont Blanc summit and safety statistics
- Nepal Mountaineering Association & Department of Tourism Nepal – trekking-peak and 8,000 m permit records
- Tibet Mountaineering Association & Pakistan Alpine Club – Cho Oyu/Everest North and K2/Nanga Parbat/Karakoram data
- The Himalayan Database (Elizabeth Hawley’s records, continued by current researchers) & Antarctic Logistics & Expeditions (Vinson)
- Operator-published rates – IMG, Alpine Ascents, RMI, Climbing the Seven Summits, Asian Trekking, Mountain Monarch, and regional operators with multi-year track records
Verification: route-level rates are cross-referenced between aggregate permit data and operator-reported outcomes; where the two differ by more than 5 points, the discrepancy is investigated and noted. Route-specific weather hazards are sourced from rescue-service incident logs rather than operator marketing. Data period: 2008-2026 · Last hub review: July 17, 2026.
Route comparison FAQ
The questions climbers ask most about choosing a line.
How much does route choice actually affect summit success?
Typically 10 to 35 percentage points between routes on the same mountain – often bigger than the guided-vs-independent gap. The largest is Kilimanjaro’s Lemosho 8-day (85%) vs Marangu 5-day (50%), a 35-point gap. On most peaks the spread reflects infrastructure (cable cars, huts, camps, itinerary length) more than technical difficulty.
What does each comparison page include?
The same 8 sections: quick comparison table, a deep-dive on each route, a decision matrix (who chooses each), weather windows compared, permit & fee differences, guided availability per route, and an explicit beginner/intermediate/expert verdict stated without hedging.
Which mountains have the biggest route impact?
Kilimanjaro (35 pts), Denali (~25 pts, West Buttress vs Cassin), Elbrus (~13 pts), Mont Blanc (~12 pts), and Pico de Orizaba (~12 pts). On technically homogeneous peaks like K2 or Everest, route choice matters less than operator quality and season timing.
Should beginners always take the easiest route?
Usually yes – the highest-success-rate, best-infrastructure route. But not always: when the standard route has structural problems for the season (e.g. Mont Blanc’s Goûter Couloir rockfall), the recommendation shifts to an alternative. Always verify current conditions.
How does the verdict differ for intermediate climbers?
It weighs success rate against experience development. The highest-success-rate route isn’t always best – intermediate climbers often benefit from a moderately harder line that builds skills for future objectives (Polish Glacier on Aconcagua, West Rib on Denali).
How is this different from the success rates hub?
The success rates hub gives aggregate per-peak data; this hub focuses on the decision between routes on a given mountain. Deciding whether to attempt a peak? Start with success rates. Already chose a peak and picking a line? Use the route comparison.
Do you cover smaller or less-famous peaks?
This hub covers 24 peaks with at least two well-established routes. Peaks with a single dominant route are covered in their climb guide instead; smaller peaks like Mount Kenya, Cotopaxi, and Lobuche East get route discussion within their guides, since their route differences don’t produce 10+ point gaps.
Hub at a glance
Choose your mountain – then choose your route
Route choice is one of the highest-leverage decisions in expedition planning: climbers who match their route to their experience, schedule, and goals run 10-35 points higher than those who default to the most-marketed line. Pick your peak from the index above, read its verdict, and climb the route that actually fits you.
