Swan Falls Dam
This area provides an access point for guided boat tours every Saturday in May and June. The Snake River cuts an incredible visual canyon, exposing black basalt towering bluffs against pale-colored sediments.
For other recreation a footbridge across the dam leads to hiking and mountain biking trails. Sinker Butte, elevation 3,421 feet, offers stunning views of the Snake River Plain and Owyhee Mountains. Trails also follow the Snake River south to Celebration Park.
