The campground features campsites for RV and tent camping, as well as excellent fishing on Arrowhead Lake, a 30-acre recreational lake stocked with bass, bluegill, crappie, channel catfish, and sunfish that features both open-water and shoreline fishing. The lake is surrounded by a two-mile nature trail suitable for hiking and biking, and features pedal boats, picnicking facilities, and an on-site general store.
