Middle Fork Of The Salmon (4 Rivers)

Salmon-Challis National Forest

Welcome to the remote and rugged mountains and rivers of Central Idaho, where over 10,000 people float the Middle Fork of the Salmon River each year. The Middle Fork is 104-miles of crystal-clear water that flows through the heart of the Frank Church - River of No Return Wilderness and is one of the original eight rivers in the nation designated as Wild and Scenic on October 2, 1968. 

The Middle Fork originates 20 miles northwest of Stanley, ID, at the intersection of Bear Valley and Marsh Creeks, and is known world-wide for extraordinary whitewater float trips. A multitude of class III and IV rapids offer boating excitement and challenge as part of a non-motorized floating experience with many technical runs. These multi-day float trips offer a wide sampling of scenic beauty along the banks, including alpine forests, high mountain deserts and a sheer, rock-walled canyon —the third deepest in North America! 

Beyond rafting, the area offers natural hot springs, prime fly fishing (catch-and-release only), scenic wilderness hikes with glimpses of prehistoric paintings and abandoned settler cabins, dazzling night skies, and geologic evidence of the river’s continuing efforts to carve its way through the Idaho Batholith. 

The Middle Fork employs a permit system to protect the river and wilderness resources from excessive human impacts. As part of that protection plan, we ask you to learn and practice “Leave No Trace” ethics. Because of the remote location, man's presence in the area was somewhat limited, leaving it in the condition we see today. In fact, there are a small number of trails, landing strips, private ranches and Forest Service stations that serve as evidence of man's intrusion. If you choose to hike from one of the river campsites, you may even be lucky enough to catch a glimpse of how past inhabitants lived!

Permit & Season Information

A float permit is required year-round to be on the waters of the Middle Fork of the Salmon River between Dagger Falls and the river's confluence with the Main Salmon. Booking a reservation here allows the individual to obtain a permit from the Forest Service to float this river. The launch date is the first day that watercraft should hit the permitted stretch of the river. 

The lottery control season extends from May 28 - September 3. 

Big Creek floaters are required to obtain a Tributary Permit from the McCall District Office, but they are not required to obtain a Middle Fork permit if they will float all the way out in one day. Big Creek is only open to floating June 1 through July 31.
