Amsterdam ⇄ the trail

Be at Gîte Michel Fagot, Les Houches on Thu 6 Aug. You finish in the Chamonix valley early afternoon on Thu 13 Aug.

✈️ Fly via Geneva fastest

  • 🛫AMS → GVA ~1 h 40 — KLM & easyJet, several daily. Morning flight = Les Houches by mid-afternoon.
  • 🚐Shuttle GVA → Les Houches (1 h 15–30, €25–55): AlpyBus, Mountain Drop-offs or Alpine Fleet. Book ahead; AlpyBus reportedly drops at the gîte's gate.
  • 💶Budget: FlixBus / BlaBlaCar GVA → Chamonix Sud (~€10–20), then valley bus or train one stop to Les Houches.

🚆 Train all the way greener

  • 1️⃣Eurostar Amsterdam → Paris (~3 h 20), cross to Gare de Lyon.
  • 2️⃣TGV Lyria → Geneva + shuttle, or TGV → St-Gervais-le-Fayet + the scenic Mont Blanc Express — stops in Les Houches, 10 min from the gîte. ~10–12 h total.

  • 🧳Michel Fagot has stored guests' spare bags before — confirm on arrival. Les Houches is 20 min from Chamonix.

🛂 Borders · money · phone know before

  • 🪪No checks on the trail, but carry your passport — Italian rifugi ask at check-in.

Weather playbook

⛈️ The August pattern

  • ☀️Mornings clear & cool (5–10 °C up high); valleys hot (25–30 °C); passes normally snow-free.
  • Afternoon thunderstorms build over the massif from midday — the one hazard to plan around.
  • On trail by 7:00–7:30 · over the day's col before ~13:00.
  • 🧑‍🌾Best forecast = the hut guardian at dinner. Apps: Météo-France mountain, MeteoSwiss.
  • 🌩️Caught out? Descend; avoid ridgelines, lone trees, cables; wait it out low.

🚦 Your go / no-go points

  • 1️⃣Col de Tricot — fair weather only (exposed col + suspension bridge).
  • 2️⃣Col des Fours — good visibility, no fresh snow. Else classic via Les Chapieux.
  • 3️⃣Mont Favre balcony — no views + mild exposure in cloud: take the valley floor.
  • 5️⃣Grand Col Ferret — no low alternative. Go very early; in a truly bad forecast, bus loop via Courmayeur–Aosta–Orsières.
  • 6️⃣Fenêtre d'Arpette — perfect stable weather only. Bovine is the all-weather route.
  • 7️⃣Bad final morning? Quick descent to Le Tour.

🥵 Heat & water

  • 🔥Sun-traps to climb early: Contamines valley (D1), Bertone climb (D4), Swiss Val Ferret (D5).
  • 💧2 L capacity; refill at every eau potable fountain and hut. Treat stream water near grazing.
  • 🧴SPF50, brimmed hat, sunglasses — alpine sun bites.
  • 🐕Patou guard-dogs (sheep, notably above La Balme): stay calm, wide berth, no waving poles.

🆘 If something goes wrong

  • 📞112 in all three countries. CH: 144 ambulance · 1414 Rega rescue. FR: PGHM Chamonix +33 4 50 53 16 89.
  • 🚁Swiss rescue is pricey — insurance must cover mountain rescue & heli evacuation in CH.
  • 🎒Always carry: offline map/GPX, headtorch, whistle, blister kit, space blanket, warm layer + waterproofs — a col can be 20 °C colder than the valley.

Hut life & practical

🛖 Refuge rhythm

  • 💤Half board ≈ €60–80 (FR/IT) · CHF 75–95 (CH). Re-confirm if arriving after 18:00.
  • 🍲Dinner fixed, 19:00–19:30. Breakfast from ~6:30.

  • 🥗Vegetarian easy if flagged ahead; vegan / GF needs advance notice at small huts.

🧭 Navigation & apps

  • 🪧Waymarking is excellent (TMB signs + the red-white blaze) — still carry offline backup: Outdooractive / Gaia / Organic Maps / AllTrails download, or a TMB GPX.
  • 🗺️Paper: IGN 3630 OT & 3531 ET, or one 1:50,000 TMB sheet.
