Boise River (Greenbelt)
Idaho's busiest tube run — Barber Park to downtown, with a city shuttle and 100,000+ floaters a summer.

These are real put-in to take-out runs, not a generic state list. Times on each river page are typical raft times at a reference flow; the live calculator scales them to today's CFS. Also live: Montana rivers.
South Fork Snake (Swan Valley)
Palisades Dam to Conant — big cutthroat water in Swan Valley before the canyon walls close in.
Float times & live CFS →South Fork Snake (Canyon)
The Conant canyon — largest remaining Yellowstone-cutthroat fishery, and no takeout in the middle.
Float times & live CFS →Henry's Fork (Box Canyon)
Island Park Dam to Last Chance — a short basalt canyon on some of the most famous trout water in the West.
Float times & live CFS →Henry's Fork (Ashton)
Below Mesa Falls — Warm River and Ashton water, slower than the Box and still packed with rainbows.
Float times & live CFS →Teton River (Driggs)
Teton Valley meadow water under the Idaho Tetons. Small, technical, and bony by August.
Float times & live CFS →Payette River (Banks)
Idaho's closest commercial whitewater to Boise. Banks to Horseshoe Bend — waves, holes, and a highway shuttle.
Float times & live CFS →South Fork Payette
Canyon water out of Lowman — hot springs on the bank, Swirly Canyon in the middle, Garden Valley at the bottom.
Float times & live CFS →North Fork Payette (Cabarton)
Idaho's hardest roadside creek. Cabarton to Banks is continuous Class IV–V — experts only.
Float times & live CFS →Salmon River (Salmon)
The River of No Return at town scale — Salmon to North Fork is a big, friendly Class I–II day.
Float times & live CFS →Salmon River (Riggins)
Lower Salmon country. Day floats past Riggins, or the multi-day Hammer Creek to Heller Bar desert canyon.
Float times & live CFS →Lochsa River
Highway 12 whitewater. A spring Class III–IV that is over by the time the rest of Idaho is just warming up.
Float times & live CFS →Clearwater River
Big, warm, summer water from Orofino toward Lewiston. A North Idaho alternative to the crowded Greenbelt.
Float times & live CFS →St. Joe River
Wild & Scenic water out of the Idaho panhandle. Shadowy St. Joe — cedar, cutthroat, and fewer people than the Coeur d'Alene.
Float times & live CFS →Selway River (Permit)
Idaho's other permit-lottery classic. 47 canyon miles, one launch a day, no cell service.
