Destination guide

Middle Fork Salmon River

A 104-mile wilderness river with continuous rapids; an open-canoe descent belongs only to expert whitewater paddlers.

Where this trip runs

Loading official route points…
Verified September 2026

This is a lottery-permit river. Only two points on the run have coordinates published by the managing agencies — the launch and the take-out — so this map stays deliberately thin rather than pinning rapids from outfitter logs. Dagger Falls sits immediately below the put-in, and the run ends at the Main Salmon confluence just above Cache Bar. Carry the Forest Service river map for rapid-by-rapid detail.

Local culture and history

Mountain Shoshone country

The Salmon-Challis National Forest's own history pages record that the Mountain Shoshone — the Sheepeater Indians — are considered the first residents of the upper Lemhi Valley, dating back 8,000 years or more, and that archaeological work shows continuous occupation across that span.

The forest also records that the Mountain Shoshone were great fishermen who built weirs and dams to catch salmon, and shared their Salmon River fishing grounds with the Nez Perce from the north and west and the Flathead from the Bitterroot Valley.
