Mountain Route Comparisons 2026: How to Choose the Right Line on 24 Major Peaks
Every major mountain has more than one way up. Generally, the choice between routes is among the highest-leverage decisions in expedition planning. Success-rate gaps of 10 to 35 percentage points are common between routes on the same mountain. Specifically, these pages break down exactly how the routes differ in technical grade, cost, weather window, permit requirements, and guided availability. Notably, every page ends with an explicit verdict naming the recommended route for beginner, intermediate, and expert climbers.
Why Route Choice Matters More Than Most Climbers Realise
Every major mountain has more than one way up. Generally, the choice between routes is often the single highest-leverage decision in expedition planning. Specifically, success-rate gaps of 10 to 35 percentage points are common between routes on the same mountain. The route-driven spread is comparable to or larger than the gap between guided and independent climbing. Notably, on most peaks the success-rate gap reflects infrastructure differences (cable car access, hut accommodation, established camps) more than terrain technical difficulty.
The data is clear. On Kilimanjaro, the Lemosho 8-day route runs 85 percent while the Marangu 5-day runs 50 percent. The 35-point gap is driven almost entirely by acclimatisation time. Generally, on Elbrus, the South Route runs 75 percent vs the North Route at 62 percent. The 13-point gap is driven by cable car access and hut infrastructure. Specifically, on Mont Blanc, the Goûter Route runs 65 percent vs the Cosmiques approach at 53 percent. The 12-point gap is driven by approach length and hut spacing. Notably, climbers focused purely on the technical character of a route often overlook the infrastructure advantage that drives most of the spread.
How to use this hub. Generally, start by identifying the mountain you’re planning. Specifically, the 24-peak index below links to each peak’s full route comparison page, with each page following the same 8-section structure for easy cross-mountain comparison. Notably, the explicit verdict at the end of each page names recommended routes for three climber profiles: beginner, intermediate, expert. Recommendations are stated directly without hedging, with the reasoning shown.
What Each Route Comparison Page Covers
Every page follows the same 8-section structure. Generally, this consistency makes peak-to-peak comparisons straightforward. Specifically, the structure starts with the quick comparison table. The page then drops into deep-dives on each route. Each page ends with an explicit verdict — which route for which climber, stated directly without hedging.
1. Quick Comparison Table
Distance, elevation gain, technical grade, average expedition days, cost difference, best season — all routes side by side in a single scannable table. The top-of-page summary that lets readers make a fast comparison before deep-diving.
2. 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. The detail layer that supports the quick comparison table.
3. Route B Deep-Dive
Same structure applied to the alternative route — so you can compare like with like at every level of detail. Where mountains have three or more routes (Mont Blanc, K2, Mexican volcanoes), each route gets its own deep-dive section.
4. Side-by-Side: Who Chooses Each Route
A direct comparison table mapping experience level, schedule, budget, and goals to the route that serves them best. The decision matrix section that does the work of matching climber profile to route choice.
5. Weather Windows Compared
How the season and summit window differ by route — including route-specific weather hazards that don’t appear in the overall mountain data. The North Route on Elbrus, for example, faces different wind exposure than the South Route during identical seasons.
6. Permit & Fee Differences
What each route costs beyond the standard permit, including hut fees, approach transport, and route-specific logistics. Some routes share permit pools (Aconcagua) while others have route-specific fees (Mont Blanc Goûter Hut bookings).
7. Guided Availability Per Route
Which routes have commercial guide support, what operators exist for each, and what the guided-to-independent rate gap looks like by route. Some routes are guided-only practical (high technical grades), while others are accessible to independent teams.
8. Verdict: Recommendation by Climber Profile
Our explicit recommendation for beginner, intermediate, and expert climbers — with the reasoning stated directly. The named-route recommendation is the value the rest of the page builds toward.
The Biggest Route Gaps in Mountaineering
Some mountains show dramatic differences in summit success rates between routes. Generally, these gaps are usually driven by infrastructure rather than terrain. Specifically, the table below shows the largest documented route-to-route success-rate spreads across the 24 mountains covered. Notably, these are the mountains where route choice has the highest impact on summit probability. Reading the route comparison page is most consequential on these peaks.
| Mountain | Routes Compared | Success Gap | Why |
|---|---|---|---|
| Kilimanjaro | Lemosho 8-day vs Marangu 5-day | 35 points | Acclimatisation time; the longer itinerary advantage |
| Mont Blanc | Goûter vs Cosmiques (technical) | ~12 points | Approach length; technical grade jump on Cosmiques traverse |
| Elbrus | South Route vs North Route | ~13 points | Cable car infrastructure on South; full self-carry on North |
| Pico de Orizaba | Jamapa Glacier vs Labyrinth | ~12 points | Glacier route safety and consistency vs labyrinth complexity |
| Rainier | DC vs Emmons Glacier | ~8 points | Infrastructure and traffic on Disappointment Cleaver vs more remote Emmons |
| Aconcagua | Normal vs Polish Glacier | ~10 points | Technical demands of glacier ice on Polish vs standard scree |
| Denali | West Buttress vs Cassin Ridge | ~25 points | Standard guided route vs expedition-grade technical climbing |
| Everest | South Col vs North Ridge | ~5 points | Roughly equivalent; primary differences are cost and crowding, not success rate |
The Kilimanjaro spread is the largest in the database. Generally, the 35-point gap between the 8-day Lemosho and 5-day Marangu reflects almost pure acclimatisation time — same mountain, same terrain, same technical demands. Specifically, this is the clearest data point in mountaineering showing how itinerary length drives outcomes. Notably, climbers booking Kilimanjaro through a budget operator offering the cheapest Marangu 5-day package are unknowingly accepting a 35-point reduction in summit probability.
The infrastructure vs technical-grade distinction. Generally, most climbers assume the “harder route” has the lower success rate. Specifically, the data shows infrastructure differences (huts, cable cars, established camps) often have larger effects on success rates than terrain technical grade differences. Notably, Elbrus North Route is barely more technical than the South Route. The North Route lacks the cable car and hut access that lifts the South Route’s success rate by 13 points. Climbers should weigh infrastructure access alongside technical grade when reading route comparison pages, not focus on technical grade alone.

How the Verdict Works
Each route comparison page ends with a three-tier verdict naming the recommended route for beginner, intermediate, and expert climbers. Generally, the verdict is stated directly without hedging. Specifically, the reasoning behind each recommendation is shown — including the trade-offs accepted and the climber profile the recommendation suits. Notably, the verdict does not always pick the easiest or hardest route. The recommendation considers success rate, experience development, cost, and the specific conditions each tier benefits most from.
| Climber Profile | Verdict Criteria | Typical Recommendation |
|---|---|---|
| Beginner First attempt, limited prior experience | Highest success rate, best infrastructure, most forgiveness for preparation gaps | Standard route (Lemosho on Kilimanjaro, West Buttress on Denali, South Route on Elbrus, Normal Route on Aconcagua, Goûter on Mont Blanc) |
| Intermediate Prior alpine experience, specific goals | Balances success rate against experience development and the specific skills the route builds for future objectives | Variable — often a moderately harder route that builds future-applicable skills (Polish Glacier on Aconcagua, West Rib on Denali, Cesen on K2) |
| Expert Technical alpinist, maximum challenge | The line that best uses the skills an expert brings — without defaulting to the hardest route for its own sake | Variable — often the most technically interesting line that matches the expert’s specific climbing background (Cassin Ridge on Denali, South Face routes on Lhotse, technical lines on Mont Blanc) |
The intermediate verdict trade-off. Generally, the highest-success-rate route is not always the best intermediate choice. Specifically, intermediate climbers often benefit more from a moderately harder route that builds skills they will need on future objectives. Notably, the route comparison pages explicitly call out the trade-off. The intermediate verdict states what skills the recommended route develops and which future objectives those skills support. This is the section where experience-development considerations get priced into the recommendation.
Sources and Methodology
Every route comparison page aggregates data across multiple authoritative sources. Generally, the goal is to avoid the operator-specific bias that creeps into single-source rate data. Specifically, route-level success rates are cross-referenced between government permit records, national park records, rescue service incident reports, and operator-published outcomes. Notably, where operator-reported rates differ meaningfully from aggregate data, the aggregate is used as the headline figure and operator-specific data is called out separately.
Primary data sources
The route comparison hub draws on the following authoritative sources. Peak-specific source citations appear on each individual comparison page.
- Argentine Park Service (APN) — Aconcagua permit records and Provincial Park summit registry.
- National Park Service (NPS) Denali — permit records, ranger station summit registry, and incident reports.
- Tanzania National Parks Authority (TANAPA) — Kilimanjaro permit records 2005-2025; the largest sample size in the dataset.
- Russian Mountain Federation — Elbrus registration records and Elbrus Rescue Service incident logs from Terskol base.
- Compagnie des Guides de Chamonix — Mont Blanc summit data and OHM (Office de Haute Montagne) safety statistics.
- Climbing Rangers — Mount Rainier NPS — Rainier permit and summit records.
- Nepal Mountaineering Association (NMA) — trekking peak permit records for Mera Peak, Island Peak, and others.
- Department of Tourism Nepal — 8,000m peak permit records and summit reports.
- Tibet Mountaineering Association — Cho Oyu, Shishapangma, and Everest North Side records.
- Pakistan Alpine Club — K2, Nanga Parbat, and other Karakoram permit data.
- Himalayan Database — Elizabeth Hawley’s foundational expedition records continued by current researchers.
- Antarctic Logistics & Expeditions (ALE) — Vinson Massif expedition outcomes.
- Operator-published rates — IMG, Alpine Ascents, RMI Expeditions, Climbing the Seven Summits, Asian Trekking, Mountain Monarch, and regional operators with multi-year published track records.
Verification process is the same on every comparison page. Generally, route-level summit rates are cross-referenced between aggregate permit data and operator-reported outcomes. Specifically, where the two sources differ by more than 5 percentage points, the discrepancy is investigated and noted. Notably, route-specific weather hazards and seasonal patterns are sourced from rescue service incident logs rather than operator marketing materials — the bias-corrected data source.
Mountain Route Comparison FAQ
How much does route choice actually affect summit success?
Significantly — typically 10 to 35 percentage points between routes on the same mountain. Route choice is among the highest-leverage decisions in expedition planning. The route effect is often comparable to or larger than the gap between guided and independent climbing on the same peak. The largest documented route spreads include two notable gaps. Kilimanjaro Lemosho 8-day (85 percent) vs Marangu 5-day (50 percent) — a 35-point gap. And Elbrus South Route (75 percent) vs North Route (62 percent) — a 13-point gap. On most peaks the success-rate gap reflects infrastructure differences (cable car access, hut accommodation, established camps) more than terrain technical difficulty. Climbers focused purely on the technical character of a route often overlook the infrastructure advantage that drives most of the rate spread.
What does each route comparison page include?
Every page follows the same 8-section structure. This consistency makes peak-to-peak comparisons straightforward. The sections cover the following ground. First, a quick comparison table covering distance, elevation gain, technical grade, average days, cost difference, and best season. Then deep-dive analysis of each route covering overview, key sections, high camps, objective hazards, and gear notes. A side-by-side decision matrix maps experience level, schedule, budget, and goals to the best route. Weather windows compared with route-specific hazards. Permit and fee differences beyond the standard permit. Guided availability per route with operator coverage. Finally, an explicit verdict names the recommended route for beginner, intermediate, and expert climbers. The verdict section states recommendations directly without hedging.
Which mountains have the biggest route choice impact on success rates?
Kilimanjaro, Elbrus, Mont Blanc, and Pico de Orizaba show the most consequential route-driven success rate gaps. Kilimanjaro has the largest spread at 35 percentage points. Lemosho 8-day 85 percent vs Marangu 5-day 50 percent — driven almost entirely by itinerary length differences between routes. Elbrus shows a 13-point gap. South Route 75 percent vs North Route 62 percent — driven by cable car access and hut infrastructure on the South Route. Mont Blanc shows a 12-point gap (Goûter 65 percent vs Cosmiques 53 percent). Pico de Orizaba shows a similar gap between Jamapa Glacier and Labyrinth approaches. On technically homogeneous peaks like K2 or Everest, route choice has smaller success-rate effects. Climbers there should focus on operator quality and season timing rather than route selection.
Should beginners always take the easiest route?
Usually yes — but not always. The recommended beginner route is the one with the highest success rate, best infrastructure, and most forgiveness for preparation gaps. This is typically the most popular standard route — Kilimanjaro Lemosho 8-day, Aconcagua Normal Route, Elbrus South Route, Mont Blanc Goûter, Denali West Buttress. Exceptions exist when the standard route has structural problems for the season (extreme crowding, current avalanche conditions, current closure status). On Mont Blanc, for example, the Goûter Couloir has had severe rockfall periods that shifted the beginner-friendly recommendation to alternative approaches. Always verify current conditions against route comparison data.
How does the verdict differ for intermediate climbers?
For intermediate climbers — climbers with prior alpine experience and specific goals — the verdict weighs success rate against experience development. The highest-success-rate route is not always the best intermediate choice. Intermediate climbers often benefit more from a moderately harder route that builds skills they will need on future objectives. Examples include the Polish Glacier on Aconcagua over the Normal Route. Or the West Rib on Denali over the West Buttress for climbers planning Himalayan peaks. The route comparison pages explicitly call out the trade-off. The intermediate verdict states what skills the recommended route develops and which future objectives those skills support. This is the section where experience-development considerations get priced into the recommendation.
How often are these route comparison pages updated?
Each page is reviewed at minimum once per year, with the spring 2026 review cycle now complete across all 24 mountains. Specific routes are updated more frequently when conditions change materially. For example, the Mont Blanc Goûter Couloir’s rockfall status is reviewed multiple times per season. The Denali West Buttress crevasse field status is reviewed at the start and middle of each climbing season. Aconcagua’s Polish Glacier ice status is reviewed annually before each southern hemisphere season. Notably, the route comparison hub footer shows each individual page’s last-updated date and next scheduled review window.
What’s the difference between this and the summit success rates hub?
The summit success rates hub presents aggregate success-rate data per peak, with route breakdowns where relevant. The route comparisons hub focuses on the decision between routes on a given mountain. The 8-section page structure (quick comparison, deep-dives, decision matrix, weather, permits, guides, verdict) helps climbers choose. The two hubs are complementary. Climbers researching whether to attempt a peak start with the summit success rates page. Climbers who have decided on a peak and are choosing between routes use the route comparison page. Most route comparison pages link directly to the corresponding success rate page for additional context, and vice versa.
Do you cover routes on smaller or less-famous peaks?
This hub covers 24 peaks that have at least two well-established commercial or commonly-attempted routes. Generally, peaks with a single dominant standard route are covered in their main climb guide. Those with no commercially viable alternatives do not get a dedicated route comparison page. Specifically, the 24 peaks indexed here represent the global set of mountains where route choice is a meaningful decision for climbers. Notably, several smaller peaks like Mount Kenya, Cotopaxi, and Lobuche East are covered in their respective climb guides with route discussion integrated. These have not been split into dedicated comparison pages. The route differences do not produce 10+ point success-rate gaps that warrant standalone analysis.
