Friday 19 June — Transfer
- After Alphubel, drive Täsch/Zermatt → Chamonix (~2.5 h, via Martigny & Col de la Forclaz)
- Overnight in Chamonix valley — rest, gear check, final forecast
Sat 20 – Sun 21 June — Rest & weather window
- Two days in the Chamonix valley — recover from Alphubel, hold acclimatization
- Easy legs only (valley walk / Aiguille du Midi viewpoint), hydrate, eat
- Lock the summit window: watch the forecast and confirm the Tête Rousse booking
Monday 22 June — Approach to the Tête Rousse Hut
| Time | Step |
|---|
| Morning | Drive/shuttle to Saint-Gervais — Le Fayet |
| ~09:00 | Mont Blanc Tramway (TMB) → Nid d'Aigle (2,372 m) |
| ~10:00–12:00 | Walk to Tête Rousse Hut (3,167 m) — ~2 h, +800 m |
| Afternoon | Check in, rest, scout the Grand Couloir crossing, early dinner, sleep |
Sleeping at Tête Rousse keeps the rockfall-prone Grand Couloir for the early morning — safer than crossing it midday on the way to the Goûter Hut.
Tuesday 23 June — Summit day
- Alpine start ~02:00–03:00 (headtorch, cold) — long day from Tête Rousse
- Cross the Grand Couloir early (rockfall zone — fast, one at a time), up the Goûter ridge to the Goûter Hut (3,835 m)
- Goûter Hut → Dôme du Goûter → Vallot Hut (4,362 m, emergency shelter)
- Bosses Ridge → summit Mont Blanc (4,806 m) — ~6–7 h up from Tête Rousse (~1,650 m)
- Descend the same route to Tête Rousse, then down to Nid d'Aigle for the tram
- Back in Chamonix — celebrate
Wed 24 – Fri 26 June — Buffer
- 2–3 spare days for a second summit attempt if Tuesday gets weathered out
- Otherwise: rest, recover, easy valley days — then drive home when ready
Book / confirm ahead
- Tête Rousse Hut — 1 night Monday 22 June, half-board — books out months ahead
- Mont Blanc Tramway tickets (Le Fayet → Nid d'Aigle)
- Chamonix valley accommodation, Fri 19 – Sun 21 June (+ buffer nights 24–26 June)
- Glacier gear — rope, harness, crampons, axe, helmet (Grand Couloir rockfall)
- Weather + condition window; guide strongly recommended on the Goûter route
- Acclimatization confirmed via Alphubel — keep hydrating between legs
The Grand Couloir is the route's main objective hazard — cross early, fast, and one at a time.
