Harriman State Park in the winter

Harriman State Park lies within an 11,000-acre wildlife refuge in the greater Yellowstone Ecosystem. Moose, Elk, and Sandhill Cranes are common, as is North America's largest waterfowl, the Trumpeter Swan. Known as one of the best fly-fishing streams in the nation, the Henrys Fork meanders for eight miles through Harriman. Over 20 miles of trails are available for hiking, biking, horseback riding, and cross county skiing.
