About
Union Flat Campground offers a shaded riverside camping experience on the North Yuba River in Tahoe National Forest. Located 6 miles east of the historic mining town of Downieville along Highway 49, the campground features 11 sites including tent-only options, standard sites accommodating small RVs up to 20 feet, and one double site for larger groups. The campground is surrounded by pine, fir, maple, and oak trees, with a historic tumbled rock wall from early gold dredging activity separating the sites from the river. The North Yuba River provides swimming, wading, and rainbow trout fishing directly from the campground. Seasonal rafting, tubing, and kayaking opportunities exist on the river. Union Flat is unique as the only campground on the North Yuba River where recreational mining is allowed; a designated area downstream permits hands-and-pans gold panning. Bears frequent the area, so campers must store all food in approved containers. Nearby attractions include the Gold Lakes Basin with over 30 miles of hiking and biking trails, the Pacific Crest Trail (accessible east of Sierra City), and Sardine Lakes about 14 miles east. The historic towns of Downieville and Sierra City offer restaurants, shops, and visitor services.
Directions
From Downieville, drive 6 miles east on Highway 49. The campground is on the right side of the highway along the North Yuba River.
