Swan Falls

Swan Falls Dam is on the Snake River about 40 miles south of Boise. It was built in 1901 to provide electricity to nearby mines. Swan Falls is the oldest hydroelectric generating site on the Snake River. Idaho Power built a new power plant in the mid-1990s. The old plant is now a museum.

The museum is open to the public, from 10 a.m. to 4 p.m. every Saturday between April 15 and Labor Day. Tours at other times may be arranged in advance by emailing us. Scheduling tours outside open hours requires at least one week prior notice. See tour guidelines.

Camping at Swan Falls

There are five designated campsites upriver of the dam including a concrete boat launch, vault toilet, picnic tables at some sites and a trash receptacle.

All campsites include fire rings and improved access roads.

Burning pallets is prohibited in and around the Swan Falls area. Violators will be asked to leave.

All camping is on a first-come, first-served basis. Visitors are asked to camp in designated areas only, due to the fragile soil and plant life in the area. Stays are limited to 14 consecutive days. Campers must obey posted campground rules and keep motorized vehicles within the posted speed limit.

Water is available at the restroom in the day-use area, but not at the campsites.
