A concrete boat ramp and slab mark this dispersed camping spot along Rock Creek near the Columbia River. The area lacks cell service and shows signs of heavy use, with one recent visitor describing the water quality as poor. Access requires driving directly to the site, though a no camping sign may restrict overnight stays.
The location sits just west of Rock Creek Park -NOW DAY-USE ONLY, which now operates as day-use only. Campers seeking established facilities might consider Sundale Park Primitive Campground seven miles east for a more developed option.
