Southwest End - WDFW

Within the Sinlahekin Wildlife Area Complex, Southwest End operates as a Washington State Department of Fish & Wildlife campground that requires advance reservations rather than first-come, first-served access. The sites sit along the Columbia River with direct water views and maintained facilities including restroom access. One visitor noted the campground's well-maintained condition and proximity to various recreational activities. The camping area operates from early May through late October, making it accessible during the warmer months when campgrounds around Conconully see peak usage.
