Summer 2024 Update:
Harriman is now participating in the Idaho Fish and Game loaner fishing rod program. Beginning Memorial Day weekend, we will begin loaning out Spin Rods with lures for use at East Harriman Fishing Pond. ** Please note that the following are the only nearby locations for Year Round Spin Fishing:
East Harriman Fish Pond; Henrys Lake; Sawtell Fish Pond. Idaho Fishing License is required for all Idaho fishing (including with loaner rods). They can be purchased at many fly shops and locations nearby. Please note Harriman State Park does NOT sell fishing licenses. A reminder that fishing on the Henrys Fork in Harriman State Park and at Osborne Bridge does not open until June 15th. Fishing on the Henry’s Fork is fly fishing only (no bait).
There is a $7 Motor Vehicle Entrance Fee (MVEF) per vehicle to visit the Park. You can purchase a 2024 Annual MVEF Pass for $80 at the Park Headquarters. Vehicles registered in the State of Idaho can purchase a $10 Idaho State Park Passport from the Department of Motor Vehicles. Daily entrance fees can be paid at the Visitor Center during the hours of 9-5 or at the main entrance outside of Visitor Center hours.
Attention: Dogs are only permitted in parking lots. There are no summer trails for use with dogs. Dogs cannot be left unattended and must always be on a six-foot leash. Department employees may impound or remove any stray or unattended animals at the owner’s expense. (IDAPA 26.01 20.175. 09)

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.
