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 on Saturdays between to the public every Saturday between April 15 and Labor Day from 10 a.m. to 4 p.m. 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.

The adjacent park is day-use only, but there are many free camping areas above and below the dam. In 2014, Idaho Power completed a major renovation of the park and the camping areas.

  • The boat ramps above and below the dam have been upgraded
  • Campsites and roads have been improved
  • Fire rings and level parking areas were added to each campsite
  • Picnic tables were added at some sites
  • New vault (no-flushing) toilets were installed
  • Additional trash facilities were added


All camping is on a first-come, first-serve basis. Visitors are asked to camp in designated areas only, due to the fragile soil and plant life in the area.

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

  • A picnic area
