PARK UPDATE:

Winter 2023-2024 Update:

Winter has officially arrived at Harriman State Park of Idaho.  The snow dances have worked to bring on the snow.

All our trails now require snowshoes, cross country skis or fat tire bikes to use.  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.

The winter access fee of $6 per person/per day or use of a Season Access Pass is now in place. These fees help with the cost of plowing and grooming our trails.

The fees can be paid at the Visitor Center during the hours of 9-5 or at the main entrance outside of Visitor Center hours.  Winter Season Access passes can be purchased for $50 for Individual, $75 for a couple pass or $100 for a family pass.

Attention: Dogs are only permitted on the Hounds Trail, which is outside of the waterfowl and wildlife refuge. 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)

While it is winter and bears are hibernating, always good practice to be Bear Aware! Remember to make noise; travel in groups only hike/bike during daylight hours.

Please be advised that Harriman State Park of Idaho will experience significant construction in the historic area during 2024-2025.

The Railroad Ranch was the full-time or part-time home of Roland and Gladys Harriman, ranch managers, cattle foremen and cowboys. Now it can be your part-time home, too. Follow the links below for more details on the various lodging opportunities in Harriman State Park. Pets are not allowed on park trails or in any of the buildings or yurts, due to the ranch being on the list of National Historic Places as well as a wildlife refuge.
