We provide all the gear, but you will need to bring your own reasonably tight climbing shoes and harness. We have belay devices, slings, and helmets, but you might prefer to bring your own. We strongly suggest bringing a down jacket, a hat, a rain jacket, a pair of comfortable approach shoes, a headlamp, and a backpack big enough for carrying lunch and gear to the crag.
There are many shops, bakeries, coffee places, restaurants, ... You won't starve here in France.
There is plenty of accommodation in Chamonix, we are able to assist you with booking some if required.
