About This Location
Harriman State Park protects over 16,000 acres of pristine habitat along the Henry's Fork of the Snake River in eastern Idaho. The park is best known as a wintering ground for Trumpeter Swans, with dozens gathering on the river's warm springs from November through March.
Summer transforms the park into a haven for mountain and riparian species. Great Gray Owls hunt the meadow edges, Sandhill Cranes nest in the wetlands, and Calliope Hummingbirds visit the wildflower-filled meadows. The park's trails wind through lodgepole pine forests alive with woodpeckers and mountain chickadees.
