Harriman State Park, Island Park

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.

  • This park is mainly used for going on horse rides. However you can go to a parking spot with great views of the river with mountains in distance. You quickly see why the head of union pacific railroad owned a good part of the land here. There is a nice 1.5 mile walk that goes along a nice lake with trumpet swans and pelicans. However, it was a little muddy for most of that hike along the lake.
  • Such a beautiful place. So many birds and beautiful wild flowers. It is well taken care of and the park rangers were very helpful and kind. They were really great with our kids too.
