The TMB or Tour of Mont Blanc is a route that can be done on foot or mountain bike. The trail crosses three countries and traverses many spectacular mountain passes.
There are numerous variations of the route possible. Riders can stay purely on mountain tracks or mix it up with roads and vehicle support.
It is possible to do the whole route by tent camping but there are mountain huts and valley hotels that accommodate many TMB riders.
As in many mountain environments during the summer, the weather can chage rapidly so be prepared. Bring a map and a well equipped bike repair kit.
