Anglers and boaters find direct access to the Columbia River at Threemile Canyon Park, where a boat ramp and dock sit adjacent to the main camping area. This Army Corps of Engineers site operates as a large gravel lot with designated spots right along the water's edge and additional overflow space for multiple RVs. The campground sits just one mile off I-84 via an easy dirt road, making it a convenient overnight stop for travelers.
The gravel surface stays level and well-maintained, accommodating rigs of various sizes in both waterfront positions and spots across from the river. A single vault toilet serves the area and stays consistently clean according to campers. The setting lacks shade, which several visitors note becomes noticeable during summer months. "Didn't hear highway noise, even though we were that close to the interstate," reports Jennifer R., though train noise carries across the water periodically.
Fishing draws many visitors to this Columbia River access point, with the boat launch seeing regular day use from anglers and water sports enthusiasts. Cell coverage reaches 2-4 bars on major carriers, allowing campers to stay connected. Wind patterns can be consistent, particularly during certain seasons, creating conditions that attract kite surfers to the area.
This pack-it-in, pack-it-out location requires campers to bring their own water and remove all trash. No campfires are permitted on site. The campground operates year-round as free camping, though the official season runs from late March through fall. Nearby Quesna County Park provides an alternative just upstream for campers seeking additional options along this stretch of the Columbia.
