Chamonix has a big international reputation as the home of not just skiing but also for adventure sports in the summer. Mountaineers can tackle the mighty Mont Blanc or the many routes around the massif. Hiring a mountain guide is highly recommended. The Chamonix valley is also a haven for rock climbers with everything from bolted sports routes in the valley to trad climbing at mid-mountain level, plus numerous bouldering opportunities. There are also a couple of Via Ferrata routes for which you don't necessarily need that much climbing experience. There are specific trails for mountain bikers to try and road cyclists will enjoy the challenge of nearby cols, Tour de France stages, and grinding up to the Emosson Dam. Paragliders fill the sky in both summer and winter giving visitors a unique view of the valley. The river Arve in Chamonix, as well as rivers over the border in Italy or Switzerland, provide rafting and canyoning adventures. In the summer, the terrain and beauty of the Chamonix Valley lends itself very well to trail runners, hikers and mountain walkers. Make use of the vast network of pathways that criss-cross the mountain sides and the valley floor - you’ll enjoy the views wherever you choose to go. Take advantage of the mountain huts along the way, they are invariably located in the best spots to admire the views. Chamonix is the traditional starting point for the Tour du Mont Blanc, a very popular hiking route that takes 7-10 days following trails through to Italy and on to Switzerland before returning to Chamonix. Several major sporting races take place each year in Chamonix, open to (athletically trained) eventers. They include mountain/trail running marathons, ultra-trails, triathlons and cycling races.
