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 104 mile-long stretch of river 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. This multi-day float trip offers 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.

Notifications and Alerts

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 closed to floating from April 1 – May 31 and from August 1 – September 30.

Outside the Lottery Control Season, the maximum group size is 24 and the maximum trip length is 8 days.   

The reservation holder will provide a complete passenger list.

This reservation is for a non-commercial permit unless the reservation holder is authorized as a commercial operator on the Middle Fork.

A maximum of 12 watercraft is allowed per permit for August 8 through September 15 launches to minimize impacts on spawning Chinook salmon.  

Groups must camp in the assigned camps listed on the permit. All group members must camp together. Although assigned to boating parties, this does not imply exclusive use. Groups may need to share camps with other Forest users. See the Campsite Selection webpage for details.  

Each group will carry and use the following required equipment (click here for more details):  

All watercraft will be clean, drained, and dry upon arrival at the launch site. Each boat will have an appropriate Idaho Aquatic Invasive Species (AIS) sticker (more details here).  

All watercraft must be inspected by Forest Service staff prior to going into the river.

A signed hard-copy permit must be obtained from the Forest Service before launching. If Boundary Creek is not staffed, boaters must stop at Indian Creek to pick up permit.

Groups will carry and display their permit upon the request of any Forest Officer. 

The Middle Fork of the Salmon River runs through the Frank Church - River of No Return Wilderness. Mechanical transport and motorized equipment are not allowed in Wilderness Areas.

Fee Policy

Reservation or Lottery Application Fee: $6.00. This fee is non-refundable.

Special Recreation Fee: All persons floating the Middle Fork of the Salmon will pay $4.00 per person per day, or have a valid Salmon Rivers Season Pass (local pass).

See Discount Pass Policies for information about Salmon Rivers Season Pass and Interagency Senior/Access Passes.

Cancellation Policy

The reservation is non-transferable. If you cannot go on your reserved launch date, you must cancel it.

If your launch date is in the control season (May 28 – Sep 3), failure to cancel by 11:59 PM Mountain Time 21 days prior to your launch date will trigger a Late Cancellation Penalty, which restricts you from holding a permit on this river for three years. To calculate the 21 days , start counting backwards, where the day before is one day prior and so on, e.g., if launch date is June 22, cancellation must occur by 11:59 PM of June 1.

Outside of control season, you must cancel at least three days prior to your launch.  

Exceptions: When water levels exceed 5.0 feet, if the road to Boundary Creek is not open, or if your control season launch is within 21 days of when you reserve it, the reservation can be cancelled three days prior to your launch date without a late penalty, but it must be cancelled to avoid a No-Show penalty.

The $6.00 reservation fee is non-refundable.
