About Middle Fork
The Middle Fork of the Salmon River is a 100-mile Wild and Scenic River flowing through the Frank Church-River of No Return Wilderness. Private permits are awarded by lottery each February for the summer season (June-September). The river drops 3,000 feet through 100+ rapids, past natural hot springs, ancient pictographs, and some of the best trout fishing in the West.
The Middle Fork of the Salmon is one of the original Wild and Scenic Rivers and the crown jewel of Idaho whitewater. About 10,000 people enter the lottery for 1,200 private launch dates. The lottery runs January 15 to February 1, with results in late February. Unlike the Grand Canyon, there's no weighted system here. First-timers have the same 12% shot as veterans.
The Experience
You launch into water so clear you can see every rock on the bottom. By midday, you've run a dozen rapids. By evening, you're soaking in a natural hot spring while dinner cooks on the beach. The canyon walls rise around you, covered in ponderosa and Douglas fir. An osprey works the river. A bighorn sheep watches from a cliff. You're 50 miles from the nearest road and won't see one for five more days.
The Middle Fork runs 100 miles from Boundary Creek to its confluence with the Main Salmon. Most trips take 5-6 days, though 4-day speed runs and 7-day relaxed trips are both possible.
The first 20 miles drop the steepest, with Velvet Falls, Powerhouse, and Pistol Creek Rapid coming in quick succession. The river mellows in the middle section, where hot springs appear every few miles: Sunflower, Loon Creek, Hospital Bar. The final push includes Rubber Rapid, Hancock, and the big one: Impassable Canyon's continuous Class III-IV stretch. You take out at Cache Bar on the Main Salmon.
