When to visit Chamonix? There are clearly two tourist seasons in Chamonix: summer, for mountaineers, hikers and mass tourism, and winter, for skiers. In spring, there's also the ski touring season, but this is a more confidential type of tourism. In all cases, you'll come across foreigners, as Chamonix is a mythical international destination. So, if it's mountain peace and quiet and low prices you're after, avoid the two tourist seasons, or pack your rucksack early in the morning to climb higher and avoid the crowds. This town, which saw the birth of mountaineering, was just a rough-and-tumble mountain village before it became a luxury resort. Hard to imagine! Several highlights punctuate the year and add to the affluence. In summer, there's the Fête des Guides, the International Climbing Festival and the Mont-Blanc Ultra-trail. In January, it's time for the Alpine Skiing World Cup. You've been warned. And yet Cham retains its superb character and undeniable appeal. Unique and majestic in its mountain setting.
