Where Mayfield Lake meets the Cascade foothills, Lake Mayfield RV Resort and Marina operates as a boat-in only facility requiring watercraft access. The resort accommodates RVs up to 50 feet with full electric, water, and sewer hookups at each site. A camp store provides basic supplies, while picnic tables and a dump station serve camper needs.
The boat-in access requirement means visitors must launch from public ramps or marinas around the lake before reaching their reserved sites. Pets are welcome throughout the property. Reservations are available for planning arrival logistics around the unique water-based entry system.
