Grab a strong coffee and fresh pastry at the station café before boarding; it’s quick and convenient. Stations cafés typically open from ~7:00am on weekdays but check the specific outlet in Martigny.
Board the regional cross‑border train (TMR/TER connection) — scenic ride through the Trient gorge and Swiss/French border; allows you to travel comfortably without driving. Typical journey time ~1h10–1h30; buy tickets at the station, SBB/MOB app or SNCF/TER site and validate if required.
Arrive Chamonix, drop luggage at hotel or luggage locker if needed and stroll the pedestrian center to orient yourself and admire the mountain backdrop. Shops and most services open by ~9:00am.
Take the famous cable car up to Aiguille du Midi for close-up panoramic views of Mont Blanc and the dramatic 'Pas dans le Vide' glass box — the highest vertical ascent by cable car in Europe. The cable car runs year-round but is weather‑dependent; in late August it commonly operates from about 8:10am to ~4:30pm, so book tickets in advance and allow 2–3 hours for ride, views, photos and café.
Return to town and enjoy hearty Savoyard cuisine (tartiflette, raclette or a mountain stew) that refuels you after high-altitude sightseeing; restaurants in town serve lunch from ~12:00–2:00pm. If you prefer a faster option, many bakeries/sandwich shops open earlier.
Board the historic Montenvers train to Mer de Glace to visit the glacier, the ice cave (seasonal), and the small glacier museum — a classic Chamonix experience. In summer the Montenvers train typically runs from about 8:30/9:00am to late afternoon (check times) and allow ~2 hours for the round trip and visit to the cave/museum.
Stroll the town center, check out outdoor shops, or have a drink on a terrace while the light softens on the mountains. Most shops and cafés stay open into early evening in high season.
Enjoy an evening meal—choose a cozy bistro for local cheese and charcuterie or a more formal Savoyard restaurant for mountain specialties; dinner service commonly starts around 7:00pm. Reservations recommended in high season.
Light breakfast at a local boulangerie — fresh croissant, coffee and juice — and pick up snacks for the day. Most bakeries open around 7:00–8:00am in summer.
Take the Brévent (or Flégère) cable cars to reach alpine viewpoints with spectacular panoramas of Mont Blanc and the Chamonix valley; excellent for half-day hikes, photography and flats/short trails. Cable cars usually begin operating around 8:30am in high season — check the Brévent/Flégère timetables before you go.
Enjoy a leisurely lunch at a mountain refuge with views (simple plates and local fare) or return to town for a wider choice of restaurants; refuge kitchens typically serve midday hours (check opening times for the specific refuge).
Spend a relaxed afternoon visiting the small but informative Musée Alpin to learn local mountaineering history (usually open ~10:00–5:00pm) or book a short spa/massage to unwind before travel.
Final stroll through town, pick up souvenirs and retrieve luggage from hotel or locker so you’re ready for the return train. Shops often close late afternoon on Sundays—plan accordingly.
Catch the regional train back to Martigny; the journey retraces the scenic valley route and typically takes about 1h15m. Purchase tickets at the station, SNCF or SBB apps and verify exact departure time for your selected train.
