PARK UPDATE:

WINTER 2025 UPDATE

  • Harriman State Park is now charging the $6 Winter Access Fee per visitor, in addition to the MVEF fee of $7. This winter access fee goes towards the park’s maintenance of plowing equipment and keeping the park accessible to the public in winter conditions, as well as grooming services and equipment maintenance. Fees can be paid with cash/check at the entrance kiosk, or inside the Visitor Center during posted staffed hours. Please be advised that due to current staffing shortages, reduced hours will be available. Trail grooming will occur 1-2 times weekly, staffing and weather dependent.
  • Harriman State Park will be undergoing extensive water and septic upgrades in 2025. This will have a significant impact on the park’s rental facilities, day use areas and parking lots. For the months of May through October of 2025, buildings that have water or septic will not be available for rental due to the construction occurring in and around them. The park’s four yurts will be available for rent through the state’s new reservations system, however. Please refer to this reservation system for the most current availabilities of the park’s rental facilities. We appreciate your patience during this period of improvement to the park’s infrastructure.

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 (CLOSED winter 2022) on weekends, offering views of Henrys Fork and its wintering wildlife. This park is generously supported by the Friends of Harriman State Park.
