Cayuse primitive campground and boat launch is located on the right bank of the Klamath River at mile 20. 9, offering river access for paddlers and anglers, though access is noted as less than ideal.

The site is situated in a scenic section of the Klamath River between Tree of Heaven and Seiad Valley, featuring Class II rapids suitable for canoes and drift boats. Cayuse Gulch enters the river just 0. 2 miles downstream of this access point.
