Lower Salmon River

The Salmon River - "Love it and Leave it Clean" - Find out how you can keep the river clean, safe and enjoyable for everyone

Whitewater boaters will find exciting rapids and spectacular beauty on this 112-mile stretch of the longest completely free-flowing river in the lower 48 states. The area’s diverse landscape and geology features a narrow basalt gorge and provides habitat for bighorn sheep, deer, elk, and a variety of raptors.

This area not only offers visitors vistas of unsurpassed beauty, but provides a snapshot of the area’s diverse history of human occupation. While traveling this river, visitors can see fragile evidence of Native American occupation of this environment for the past 10,000 years including prehistoric homesteads, Chinese mining claims, Nez Perce Indian sites, rock structures, pictographs, stone artifacts, graves, mines, picks, shovels, ditches, and trails. This stretch of the river has also been recommended for “National Wild and Scenic River” designation.
