Harriman State Park

Harriman State Park is a recreation area in eastern Idaho covering about 11,000 acres, extending through a scenic valley with meadows, forests, and eight miles of the Henry's Fork river. The land features open grasslands mixed with wooded areas and diverse habitats.

Railroad investors from Union Pacific purchased this land in 1902 and operated it as a ranch and private retreat until 1977. Afterwards, the property was converted into a public park.

The park displays old buildings and structures that show how early 20th-century ranchers lived and worked on this land. Walking through the grounds, visitors can see how people shaped this place over generations.

The park has an extensive trail network for hiking, biking, and horseback riding in summer, while winter allows for cross-country skiing. Access is available year-round, though conditions vary by season.

About two-thirds of all trumpeter swans in the contiguous United States choose to winter in the waterways here. This makes the park a critical refuge for these large white birds.
