When Upper Pines and the Yosemite Valley campgrounds sell out in minutes, the Yosemite/Mariposa KOA is where savvy campers land. Located in Midpines on Highway 140, 45 minutes from Yosemite Valley, it sits along the Merced River and offers what no Yosemite Valley campground can: a swimming pool, full hookups, reliable hot showers, and a stocked camp store. The Highway 140 (El Portal) approach also avoids Highway 120 congestion and gives direct access to the scenic Merced River Canyon.
