Jackson Hole has two peak seasons: ski season runs roughly late November through early April, when Jackson Hole Mountain Resort delivers legendary steep terrain and deep powder. Summer (June through September) is prime for Grand Teton and Yellowstone National Parks, wildlife viewing, hiking, and Snake River rafting. The spring and fall shoulder seasons are quieter and cheaper, though some park roads have limited access.
