Harriman State Park was deeded to the people of Idaho by Roland Averell Harriman, who stipulated that the park would be preserved for the enjoyment of future generations. It was opened as a park in 1982.
The ranch, with its original structures, offers guided tours during the summer. Wildlife abounds at the park, with elk, moose, beaver, muskrats, bald eagles, osprey, trumpeter swans, and other waterfowl frequently seen.
Henry's Fork, a world-famous fly-fishing stream, winds through the meadows of Harriman State Park.
The park is open year-round for day use only.
Many of Idaho's most beautiful and scenic spots are preserved in the Idaho State Parks system.
