The Chamonix valley offers 350 km of marked hiking trails, a lift network that can shortcut up to 1,000 m of climbing, and the most dramatically scaled mountain backdrop in western Europe — but it also sits at the base of a 4,808 m peak surrounded by active glaciers, and the weather here turns faster, and more violently, than almost anywhere else in the Alps.
Most of the best hikes in Chamonix take place on one of two flanks of the valley: the Aiguilles Rouges massif to the north — granite ridges, high lakes, and the iconic Lac Blanc — and the Mont Blanc massif to the south, where the Grand Balcon trails track parallel to the glaciers at 1,900–2,300 m. The valley floor itself offers well-maintained riverside paths, while the cable cars and the rack railway to Montenvers unlock terrain that would otherwise demand serious fitness and a full day of climbing from the valley floor.
What sets Chamonix apart from most hiking destinations is that the experience scales from very easy to genuinely serious within the same valley. You can walk from the town centre to the edge of the Mer de Glace in under three hours. The following day you can spend eight hours on the Grand Balcon Nord at 2,300 m. Both are valid — but they require very different preparation. The ten routes below cover that full range, from a family gorge walk near Servoz to the five-day Tour des Aiguilles Rouges circuit through three nature reserves.

The Best Hikes in Chamonix
The ten routes below run from easy valley-floor walks to a demanding five-day circuit above 2,900 m. The first three require nothing more than decent footwear. From Route 4 onwards, the Chamonix lift network becomes a genuine asset — several routes only make sense with a cable car start or finish, and knowing which lifts are running (mid-June to mid-October for most) changes the planning entirely. For anything above 2,000 m, check the Office de Haute Montagne daily conditions bulletin before you leave — afternoon storms build fast, and the high cols are no place to be caught without waterproof gear.
1. Gorges de la Diosaz
Distance: 4 km return
Duration: 1h30
Elevation gain: ~150 m
Difficulty: Easy
Eight kilometres west of Chamonix, near the village of Servoz, the Gorges de la Diosaz cut a narrow limestone channel above a succession of waterfalls — the longest dropping around 40 m into a series of pools. Wooden walkways and footbridges guide the route above the torrent, making it accessible for families and hikers of any fitness level. It’s a paying attraction (~€8 adults / €5 children), which keeps the path impeccably maintained and the flow of water well-explained. The gorge opens mid-June and closes in October; visit early in the day to have the narrowest sections to yourself.
2. Mer de Glace — Montenvers Descent
Distance: 6.6 km (one-way descent)
Duration: 2h30
Elevation: +218 m / −924 m
Difficulty: Easy–Moderate
Take the Montenvers rack railway (built 1909; ~€40 return) from Chamonix station up 870 m to the historic hotel and viewing terrace at 1,913 m, then walk back down through old-growth spruce and larch forest on a well-marked trail. The route descends ~500 steps at the glacier access point — a number that has grown dramatically as the Mer de Glace retreats, falling around 150 m lower at the access point than it stood in the 1990s. That retreat is visible and sobering, and it makes this route worth doing at least once. The descent takes about 2h30; alternatively, take the train both ways and allow an hour at the top to absorb the scale of the glacier below.
3. Vallon de Bérard & Cascade du Bérard
Distance: 9 km return
Duration: 3h
Elevation gain: ~450 m
Difficulty: Moderate
Starting at the Col des Montets (1,461 m) — reached by bus from Chamonix in about 20 minutes — this valley walk follows the river Bérard south through the Réserve Naturelle du Vallon de Bérard, climbing gently through open woodland before opening into the wider alpine valley. The cascade at the upper end drops around 30 m into a rocky basin and makes a natural turning point. The terrain is benign and the path well-marked throughout; it’s well-suited to families with older children. Note the reserve rules: no dogs, no camping, no picking plants. The Col des Montets trailhead is served directly by Chamonix Bus — no car needed.
4. Lac Blanc via Flégère
Distance: 8.05 km return from Flégère
Duration: 4h05
Elevation gain: +615 m
Difficulty: Moderate
The most popular day hike in the Chamonix valley, and the one that earns its reputation most fully. The Flégère cable car (from Les Praz, a short bus ride from town; ~€25 return) lifts you to 1,877 m, from where the path climbs 475 m across rocky terrain — including a short section of metal ladders below the lake — to reach Lac Blanc at 2,352 m. In still conditions, the lake reflects the entire Mont Blanc massif with photographic precision. The refuge at the shore does a good lunch and is worth the longer stop. Note that a section of the approach near the top includes fixed metal ladders: fine for confident walkers but worth knowing about in advance. Book the cable car online for July–August; the queue otherwise can be long.
5. Grand Balcon Sud — Flégère to Planpraz
Distance: ~5.5 km (point-to-point)
Duration: 2h30
Elevation gain: ~345 m from lift top station
Difficulty: Moderate
The Grand Balcon Sud traverses the north flank of the Chamonix valley at around 2,000 m, with uninterrupted views south across to the Mont Blanc massif as the path contours between the Flégère and Planpraz lift stations. Walk it point-to-point from Flégère west to Planpraz — the Chamonix Aiguilles and the glaciers below fill the skyline directly ahead for the entire route. The Flégère cable car from Les Praz handles the ascent, and from the top station the path is wide, well-signed and technically forgiving, with just one short section of fixed metal steps. Descend from Planpraz on the Brévent gondola back into Chamonix town.
6. Aiguillette des Posettes & Col de Balme Loop
Distance: ~12 km loop
Duration: 5h on foot
Elevation gain: ~880 m
Difficulty: Moderate–Strenuous
Starting from the hamlet of Le Tour at the upper end of the valley, this loop climbs to the Col de Balme (2,204 m) — the French–Swiss border — before continuing to the summit of Aiguillette des Posettes at 2,201 m, where a full 360° panorama opens up: the Mont Blanc massif to the south, the Trient plateau into Switzerland to the north, and the Glacier du Tour and Refuge Albert 1er below to the east. The Charamillon gondola (~€22 one-way) cuts the ascent by around 600 m if you want to reduce the effort; the on-foot version is fully satisfying but a solid day out. Either way, this is one of the most complete views available in the valley from a hiking trail.
7. Refuge Albert 1er & Glacier du Tour
Distance: 8.3 km
Duration: 4h30
Elevation gain: +750 m
Difficulty: Moderate–Strenuous
The only CAF refuge in the Chamonix valley reachable without crossing a glacier — a distinction that matters more than it sounds in a massif where most high terrain involves ice. Starting at Le Tour and using the Charamillon gondola plus Autannes chairlift combined (~€27), you climb through high pasture to the refuge on the right moraine of the Glacier du Tour at 2,702 m. The terrace view at the refuge takes in the Aiguille du Tour, Aiguille d’Argentière, and the broad couloir systems above the ice — one of the most impressive high-mountain panoramas accessible to non-mountaineers in the entire massif. Plan to spend time at the top; the 2h30 round trip from the upper lift station is a short walk for what it delivers.
8. Grand Balcon Nord — Montenvers to Plan de l’Aiguille
Distance: 18.5 km (point-to-point)
Duration: 7h15
Elevation gain: +675 m
Difficulty: Strenuous
Part of the Tour du Mont Blanc and the GR TMB, this high traverse tracks the north flank of the Mont Blanc massif at 2,000–2,300 m from Montenvers (Mer de Glace train, 1,913 m) to the Plan de l’Aiguille mid-station on the Aiguille du Midi cable car (2,310 m). Over 18.5 km, the route passes the Refuge du Montenvers, crosses the Chapeau viewpoint above the receding glacier, and delivers sustained close-up views of ice and granite that most day hikers never reach. This is a full day out — start from Montenvers at 9am and you’ll reach Plan de l’Aiguille mid-afternoon, in time to take the cable car down. Recommended approach: train up to Montenvers, walk the Grand Balcon, cable car down from Plan de l’Aiguille.
9. Le Brévent Summit Hike
Distance: ~11 km return
Duration: 5h30 (ascent)
Elevation gain: ~1,400 m
Difficulty: Strenuous
The Brévent cable car is one of Chamonix’s great landmarks — and the summit bar at 2,525 m is famously busy in high season. But hiking to the top from the valley floor is a different proposition entirely: 1,400 m of sustained climbing on a clear path, the final section on loose rock requiring care and decent footwear. The reward is a summit panorama that places Mont Blanc at eye level across the valley — a perspective that feels earned rather than purchased. Take the Planpraz gondola from town to reduce the climb by ~700 m if you want a more moderate approach; the final ridge from Planpraz to the summit adds around 450 m in about 2 hours. Descend by cable car if tired — the Brévent lift runs until early evening in season (~€30 one-way from summit).
10. Tour des Aiguilles Rouges (4-Day Circuit)
Distance: ~49 km
Duration: 4 days
Elevation gain: +4,559 m
Difficulty: Expert / Multi-day
The Tour des Aiguilles Rouges is a four-day counter-clockwise circuit starting and finishing at Col des Montets (1,461 m), looping through three nature reserves on 49.4 km with +4,559 m of elevation gain. The stages connect Refuge du Lac Blanc (2,350 m), Refuge de Bellachat (2,166 m) and Refuge de Moëde Anterne (1,993 m) before crossing Col de Salenton (2,526 m) on the final day back to Col des Montets. Expect ibex on the Bellachat stage, a wild passage behind Le Brévent on Stage 3, and the foot of Le Buet, thought to be the first high mountain summit climbed in the Alps, on Stage 4. Book all refuges well in advance for July and August.
