Very popular class IV run. It is 45 min from Boise, roadside, and therefore a popular evening run with the locals. The first 2-3 miles are with entertaining rapids and wave trains, then Staircase a long class IV rapid followed by a long sections of flat water, and finally Slalom another long class IV. It is almost always possible to 1) hitch a ride for the shuttle, 2) hook up with other people going down the river.
