Corn Creek is the mandatory put-in for all permitted floats through the Frank Church River of No Return Wilderness on the Main Salmon River, featuring an 18-site campground at 2,900 feet elevation with a boat ramp, vault toilets, and hand-pumped water.

Located 45 miles west of North Fork via Forest Road 030, the facility serves as the gateway to Class III-IV whitewater rapids and includes hiking/horse trails looping to Butt Creek Point and Horse Creek Campground.

River permits are required year-round for floating the Wild section downstream, and the remote access road is subject to winter snow closures.
