Island Park / Ashton
The same natural forces that made Yellowstone so scenic have made Island Park similarly beautiful. Upon leaving the the agricultural Upper Snake River Valley outside of Ashton, you'll actually drive up the edge of an ancient collapsed volcano. The heart of Island Park is Harriman State Park.
4,330 acres of pristine forest land and high-country meadows. Located in the center of a 16,000 acre wildlife refuge. The park is a haven to rare trumpeter swans, numerous waterfowl, elk, deer and other wildlife. The world famous fly fishing stream, Henry's Fork of the Snake River, winds through the meadows of the refuge.
