Annual LMC alps meet. Overwhelming choice of classic rock climbing and mountaineering at all grades.
Closest airport is Geneva
Staying at the Camping Du Glaciere in Argentiere. No booking required.
Car hire optional as the public transport up and down the Chamonix valley is sufficient to get into town and to lift stations etc. Plenty of reasonably priced transfer services operate between Geneva airport and Agentiere.
