Chamonix: visitor guide

Chamonix is a working valley town, not a purpose-built resort: the lifts, the trains and the trails start from the streets. The Aiguille du Midi cable car climbs to 3,842 m in about 20 minutes and runs year-round, weather permitting; the Montenvers railway reaches the Mer de Glace glacier viewpoint, and the Brévent–Flégère and Grands Montets lifts serve the ski and hiking terrain on either side of the valley.

Tickets are sold per lift or as multi-day area passes, and prices change by season, so treat any figure as a 2026 estimate and confirm on the operator's site. High-altitude lifts close in strong wind, and the Aiguille du Midi often sells out on clear summer days: book a timed slot in advance. The valley's own ski season runs roughly mid-December to mid-April, with high terrain holding snow later.

Most overseas visitors fly into Geneva (GVA), about 90 km away, then take a shared shuttle, private transfer or bus; allow roughly 1h15–1h45 depending on traffic and the border. Some services run from Geneva airport directly to Chamonix hotels, which is the simplest option with luggage or ski bags.

By rail, the classic route is a TGV or regional train to Saint-Gervais-les-Bains/Le Fayet, then the Mont Blanc Express narrow-gauge line up the valley to Chamonix. From Paris this is a half-day journey with one change; check connections, because the last valley train leaves in the evening. Driving from Geneva or Lyon is straightforward in summer; in winter carry chains or winter tyres and check pass conditions.

June to September is the hiking season: trails from the valley floor up to the high refuges, lifts open for walkers, and long daylight. July and August are the busiest and priciest weeks, with afternoon thunderstorms common in the mountains. September is often the best balance of stable weather, quieter trails and open lifts.

December to March is for skiing and snowboarding, with February school holidays the peak. Late December and New Year are busy and expensive. May and November are the quiet shoulder months, when some lifts, huts and restaurants close for maintenance; if your trip depends on a specific lift, check its opening dates before booking.

The valley is a chain of villages: Les Houches, Les Bossons, Chamonix centre, Les Praz, Argentière and Le Tour, each with its own lifts and character. Staying in Argentière or Les Praz can be cheaper and quieter than the centre, with buses linking them.

Beyond the valley, Annecy and its lake are about an hour and a half by road, Geneva about an hour, and the Aosta Valley in Italy is reachable through the Mont Blanc Tunnel. Lyon and Turin are both roughly three hours away by road or rail, which makes Chamonix a workable stop on a longer Alps itinerary.

Buy lift tickets online for the days you need them rather than a season pass, unless you are skiing every day. Mountain weather changes fast: start hikes early, carry a shell and water, and turn back if clouds build. The valley buses are free or cheap with a guest card from many hotels, so ask at check-in.

Altitude matters at the Aiguille du Midi: 3,842 m is high enough to cause headaches and breathlessness, so keep the visit short if you feel unwell and do not go up on your first morning. For the Mer de Glace, note that the glacier has retreated and the access stairs are long; allow more time than the old guidebooks suggest.
