About
Hammerhorn Lake Campground is a small, remote facility located approximately 18 miles north of Eel River Station via M1 Road (Indian Dick Road) in eastern Mendocino County. The campground was destroyed in the 2020 August Complex fire and suffered additional damage during subsequent winter storms. After extensive restoration work completed in partnership with California Deer Association and Patriot Restoration Ops, the campground reopened in September 2025. The campground features nine campsites situated in a mixed conifer forest with hardwood trees and shrubs, positioned a short distance above a five-acre lake. Facilities include vault toilets, fire rings, and picnic tables donated by the Ukiah Chapter of the California Deer Association. One accessible campsite and bathroom are available. The campground includes one pull-through site suitable for trailers, though the access road is unpaved. The lake is stocked with trout in early summer by the California Department of Fish and Wildlife, providing fishing opportunities throughout the season. An accessible trail around the lake is approximately 40 percent complete. The remote setting offers solitude and scenic views in a recovering post-fire landscape. The campground operates seasonally and closes for winter, typically from early November through late spring or early summer depending on snow conditions.
