State Park

Harriman State Park lies in the heart of a 16,000-acre wildlife reserve in the Greater Yellowstone Ecosystem. This sanctuary protects a diversity of birds and mammals similar to those living in nearby Yellowstone National Park.

The rich wildlife habitat has been preserved since the turn of the century when the owners established a private hunting reserve and working cattle ranch. For 75 years, the ranch maintained healthy game, waterfowl and fish populations, allowing today’s park visitors to observe a rare concentration of wildlife in its scenic, natural surrounding.

Twenty-seven of the original Railroad Ranch buildings, from the cookhouse to the horse barn, are still intact, furnished and carefully maintained.
