The best time to camp, hike, and mountain bike at Whistler is May through early October. Fall is especially nice, with somewhat fewer crowds and vibrant color in the trees. May and June are often less busy, too, although they tend to bring more rainy days. Snow typically starts to fall in November and lingers at high elevations into summer. Whistler-Blackcomb normally opens for the ski season around the U.S. Thanksgiving week and closes in April.
