Harriman State Park is a state park in eastern Idaho, United States. It is located on an 11000acre wildlife refuge in the Greater Yellowstone Ecosystem and is home to an abundance of elk, moose, sandhill cranes, trumpeter swans, and the occasional black or grizzly bear. Two-thirds of the trumpeter swans that winter in the contiguous United States spend the season in Harriman State Park. The land was deeded to Idaho for free in 1977 by Roland and W. Averell Harriman, whose insistence that the state have a professional park managing service helped prompt the creation of the Idaho Department of Parks and Recreation in 1965. The park opened to the public in 1982. It is located in Fremont County, 3mi south of Island Park, Idaho. Henry's Fork, a fly-fishing stream, winds through the meadows of Harriman State Park. In winter, many of its roads and trails are groomed for cross country skiing.The park is located within a geological feature called a caldera, the Henry's Fork Caldera.Friends of Harriman State Park, Inc/ is a 501(c)(3) organization dedicated to community projects that directly benefit Harriman State Park of Idaho. Friends of Harriman State Park was formed in the winter of 2010 after the announcement by the State of Idaho of the need to cut park funding completely and eventually dissolve the Idaho Department of Parks and Recreation into another state agency.To visit Harriman State Park on your holiday in Island Park, and find out what else Island Park has to offer, use our Island Park trip generator.

It has nice trails for cross-country skiing in the winter. When my wife and I went, it seems that we had the whole place to ourselves.
Harriman Park is beautiful any time of year. We love to bike here in the summer and snow shoe in the winter. Waterfowl are plentiful and you never tire of the beauty of this State Park. Truly heaven on earth!
Great place for Mountain biking. Bring your fish pole! Very close, like 3ish miles from Riverside Campground and you can access from snowmobile trails, instead of riding Hwy 20!
So much fun. Beautiful scenic views.
it's a pretty view and easy short flat hike, but there is a plethora of bugs everywhere. i left with tons of bug bites and they bugs are frankly not inviting me to go back.
