Season by season
Spring (Mar–May)
Comfortable hiking, wildflowers and a chance of bison calves. Storms arrive by May.
Summer (Jun–Aug)
Very hot by mid-morning. Stick to dawn and dusk. Bats use the Clarity Tunnel in this season.
Autumn (Sep–Nov)
Perhaps the best time: cooler air, clear light and calm campgrounds.
Winter (Dec–Feb)
Cold nights, quiet trails and bison in their thick coats. Bring warm layers.
