About
Spillway Campground sits at the southern end of Letts Lake within Mendocino National Forest, about 19 miles west of Stonyford. This intimate 9-site loop (sites 34-42) is part of the larger Letts Lake recreation area, which encompasses 42 total sites across four distinct loops. The campground occupies a forested setting near the shores of a scenic 35-acre mountain lake. The lake is the primary attraction, supporting non-motorized boating, swimming, and trout fishing. A fully accessible fishing pier makes angling easy for visitors of all abilities. A one-mile trail circles the lakeshore, offering gentle hiking with lake views. Each campsite is equipped with a fire ring and picnic table, and the area is served by accessible vault toilets. Potable water and trash service are available only during the primary season from Memorial Day through Labor Day. During shoulder seasons the campground remains accessible at a reduced fee, but campers must bring their own water and pack out trash. The campground operates first-come, first-served with no advance reservations. Payment is made on-site via QR code through the Recreation.gov app.
