You will have a great time in Chamonix. Its climber's paradise. Perfect for bouldering, top roping and free climbing. Its also great for mountaineering but May is probably too early for a summit attempt.

 

My suggestion is to hook up with some guides who know the Mont Blanc Massiv real well. They can take you to some great places. I used a Swedish guide for two weeks. I was the leanest and fittest I have ever been and learned a huge amount.

 

Summiting Mont Blanc was tough though. I slept for 20 hours when we eventually made it down to Chamonix. Worth it though, the views and crevasses were amazing.

 

Be very careful, Mont Blanc is a dangerous mountain and claims approximately 100 lives a year. People think it is easy but it isn't. Have a great trip. 

 

Just call me Tigasin. That's what I'm talking about
