📖 Essential Reading Before You Go: Read the Ultimate Guide to Backcountry Emergencies in Chamonix before attempting this or any backcountry route in the valley.

The Col des Rachasses sits high above the Chamonix Valley — a winter sunset spot that's both thrilling to reach and genuinely unforgettable once you're there. Golden light over Mont Blanc, the Aiguilles Rouges glowing behind you, and the Argentière Glacier catching the last of the day. This guide covers everything you need to get there safely and make the most of it.

"A sunset that makes every winter's effort worthwhile — golden light over Mont Blanc, the valley far below, and a powder descent still to come."

Two Routes to the Col

There are two main approaches to the Col des Rachasses, both starting from lifts on the Grands Montets side of the valley. Choose based on your fitness, time available, and conditions on the day.

Route 1 · Shorter

Via the Bochard Gondola

Vertical gain~300m
DifficultyAdvanced
CramponsRecommended

Take the Bochard gondola to the top. Start descending the piste and make a right cut as soon as possible, traversing below a rocky section to a flat area — skins on here. Climb diagonally left, zig-zagging as you near the col. The final stretch can be steep and icy; ski crampons are strongly recommended for this section.

Route 2 · More Direct

Via the Herse Chairlift

Vertical gain~400m
DifficultyAdvanced
TraversingLess required

From the top of the Herse chairlift, skins on and head straight up. You'll intersect the Bochard tracks on the way up. More direct with fewer traverses — a slightly longer ascent but a more straightforward line for those who prefer it.

🎿 Navigation: The col is identified by a small notch in the ridge with a nearby wooden ski patrol hut. Aim for that notch — it's visible from partway up on both routes once you're above the rocky section.

At the Col

The Old Ski Patrol Hut

Position yourself by the hut, facing west. The sun drops behind the Mont Blanc Massif, casting the final golden light across the valley. Behind you, the Argentière Glacier catches the last colours of the day. One of the finest viewpoints in the Chamonix area — and almost nobody else is here.

The Sunset View

Once at the col, position yourself by the old ski patrol hut, facing west. The sun casts its final golden light over the Chamonix Valley — the Mont Blanc Massif ahead, the Aiguilles Rouges range lit from the side, and behind you, the Argentière Glacier glowing in the last of the alpine alpenglow.

The golden hues against snow-capped peaks make this one of the most peaceful and visually dramatic moments the valley offers. Crowds are non-existent. The silence is complete. It's worth every step of the ascent.

The Descent

As the sky shifts to deeper hues you'll still have time for a powder descent. Two options: return along your ascent route and find your line back to the piste, or cross the col itself and descend left along the line of the old piste. Either way, the regular route takes you back to the piste for a safe journey to the bottom.

⚠️ Grooming machines: The descent often overlaps with active slope grooming. Be aware of piste machines in operation, especially as daylight fades and visibility decreases. Give them a wide, visible berth.

Time Needed

Getting the timing right is the difference between a good experience and a great one. Plan your lift times backward from sunset, not forward from the car park.

🎿
Ascent
30–60 minutes depending on fitness and route choice
🌅
Golden Hour
~1 hour before sunset — but the sun drops behind the mountains earlier in Chamonix
🕐
Buffer
Add 15–20 min of margin — always better to arrive early than to rush the final pitch
💡 Timing tip: Check sunset time for the valley the night before and work backward. The sun disappears behind the massif 20–30 minutes before the listed sunset time — factor this in when planning your lift schedule.

Safety Essentials

This is a backcountry route above an active ski area. It demands proper preparation and the right gear. Do not attempt it without experience in off-piste and touring terrain.

📡

Avalanche Transceiver

Switched on and worn — not in a bag. All members of your group should carry one and know how to use it.

🔨

Shovel & Probe

Non-negotiable for any backcountry terrain. Compact and lightweight — no excuse not to carry them.

🧊

Ski Crampons

The final section to the col can be steep and icy. Crampons make the difference between a safe ascent and a dangerous one.

🔦

Headlamp

Essential for visibility during the descent in fading light. Bring one even if you plan to be down before dark.

📱

Fully Charged Phone

With a detailed map or GPS app downloaded offline. Cold temperatures drain batteries fast — keep it close to your body.

🎒

Water & Food

Bring more than you think you need. A descent in failing light or unexpected conditions takes longer than planned.

⚠️ Important safety notice: This route is for advanced skiers who are confident and experienced in backcountry and off-piste terrain. Only attempt it if you are capable of handling steep, icy, and challenging conditions in changing light. Ski responsibly. Chamonix Prints assumes no responsibility for accidents or incidents on this or any other mountain route.
Frequently Asked Questions
No — this is an advanced backcountry route. The terrain is steep and can be icy, the final section to the col is exposed, and the descent is off-piste. It requires confidence in challenging, variable conditions and experience with ski touring gear. If in doubt, hire a qualified mountain guide through the Compagnie des Guides de Chamonix.
A guide is not required but is strongly recommended for anyone who hasn't done significant backcountry touring before. The Compagnie des Guides de Chamonix can arrange guided ski touring experiences in the area. A guide will also be able to assess avalanche conditions on the day, which is knowledge that's difficult to replicate without local expertise.
Avalanche risk varies depending on recent snowfall, wind loading, and temperature. Always check the daily bulletin from Météo France (meteo.fr) before heading out — it provides a risk rating and detailed information on aspect and elevation. Even at moderate risk levels, the terrain on this route can present hazards. Do not go in risky conditions without expert local knowledge.
Both routes start from the Grands Montets area — Route 1 via the Bochard gondola, Route 2 via the Herse chairlift. Check current lift operating times on the Chamonix ski area website before your visit, as last lift times vary by date and season. Missing the last lift down means you must ski the full mountain — factor this into your planning.
Call 112 (European emergency number) or 15 (SAMU) for mountain rescue in France. The PGHM (Peloton de Gendarmerie de Haute Montagne) handles mountain rescue in Chamonix. Read the full backcountry emergencies guide linked at the top of this page before heading out — it covers what to do in detail.
