"Tour du Mont-Blanc" (TMB) is a medium-distance loop route in the Alps. The route runs through France, Italy and Switzerland. The entire trail is well signposted and offers guarded mountain refuges that provide anything necessary. It is advisable to reserve a place and bear in mind that at the end of August there is the Ultra Trail which follows the same itinerary and does not allow, during those dates, to reserve in the refuges. Impressive views of the Mont-Blanc massif and its glacier.
