Mont Blanc Guided Ascent via Aiguille du Gouter

Pack functional clothing for alpine conditions: a Gore-Tex or other waterproof breathable jacket, waterproof rain pants, a warm jacket (down or preferably Primaloft), a light fleece, quick-dry short-sleeve shirts, slightly thicker stretch pants for cold days or nights, trekking pants, thermal top and bottom, plus underwear and spare clothes.

Bring climbing equipment including crampons, a climbing harness, three locking carabiners, one 120 cm sling, an ice axe (55–66 cm), and a climbing helmet; if you don’t own gear you can rent it in Chamonix—check local rental shops.

For head protection pack a light running cap, a wool hat, a neck gaiter, and a ski mask, and for hands bring thin fleece gloves, leather gloves, and heavy-duty thermal gloves or mittens.

For your feet bring two pairs of merino ski socks (one thin, one thick), light trail shoes or hiking boots (whichever you normally use), and gaiters if they’re not integrated into your boots.

Carry a 30-liter mountain backpack and a small travel bag for documents and wallet.

For hut stays bring a silk sleeping bag liner (mandatory in most mountain huts) and ear plugs.

Take accessories such as a headlamp with spare batteries, sunscreen, lip balm, and after-sun lotion.

For food and drink bring at least a 1-liter water bottle or thermos and snacks like nuts, gels, hydration/energy bars, protein bars, trail mix, magnesium tablets, and recovery supplements.

Finally, pack travel essentials including casual clothing, ID or passport, visa/payment cards, cash, insurance documents, vaccination card, a microfiber towel, a first-aid kit and personal medication, an emergency thermal blanket, a mobile phone and GPS watch with route track, plus a power bank, camera, charging cables, headphones and optional items like a selfie stick.
