Centerville Flat Campground is a hidden gem in Northern California. With just nine campsites, this first-come, first-served campground offers a peaceful escape with stunning views of the Trinity Alps. Visitors can enjoy hiking, fishing, and swimming in the nearby Trinity River. The campground has vault toilets, picnic tables, and fire rings, but no potable water or trash service, so visitors must pack out their own trash. The best time of year to visit is from late spring to early fall, with average temperatures ranging from the low 70s to high 80s.
