About the Park

Harriman State Park lies within a 16,000-acre wildlife refuge in the Greater Yellowstone Ecosystem. Known for its beautiful scenery and wildlife, Harriman State Park offers 22 miles of hiking, mountain biking, and horseback riding trails that slink through meadows, meander along river banks and through lush evergreen forests. Some of the best fly fishing waters in the nation flow through eight miles of Harriman State Park, known by anglers all over the world over as “the Ranch.” Moose, elk and Trumpeter Swans, the world’s largest waterfowl species, are a common sight at Harriman.

Owned by Union Pacific Railroad investors from 1902 to 1977, the park acreage served as a cattle ranch and private retreat for the Harriman and Guggenheim families. Today, Harriman State Park provides visitors a perfect setting to enjoy the unique history and natural beauty of the area.

Visitors can stay overnight in Harriman’s unique overnight facilities, such as the rustic Yurts or Ranch Manager’s House. Harriman’s rental facilities are perfect for family events, weddings, retreats and learning conferences. During the summer, tours of the historic Railroad Ranch buildings and interpretive nature programs are offered on weekends and holidays by our knowledgeable park rangers. Winter activities include over 24 miles of groomed Nordic skiing trails, snowshoeing, and fat biking. The historic Jones House serves as a warming hut on weekends, offering views of Henrys Fork and its wintering wildlife. This park is generously supported by the Friends of Harriman State Park.
