Stinson Flat is a primitive riverside campground on the Klickitat River featuring a basic boat launch with armored gravel access suitable for fishing and paddling. The campground is accessed via a steep, challenging 1.

1-mile gravel road with significant grade and washboard surface (best for tent camping), and offers minimal amenities including one vault toilet, no hookups, and no potable water—bring your own supplies.

Open campfires are permitted except during the seasonal burn ban (June 1–October 12), and a Discover Pass or Vehicle Access Pass is required.
