Afterbay Fishing Access Site is the first public boat launch below Yellowtail Dam, featuring a well-maintained ramp with overflow parking for busy seasons and adjacent campground facilities.

The site provides access to the upper 13 miles of the Bighorn River and experiences heavy use during peak season (April-October), with a short float to 3 Mile Access and onward to Bighorn Access.

Wade anglers can also access the river here, though most surrounding land is private and anglers must stay below the high-water mark.
