Mayfield Lake campground with 101 numbered vehicle sites across full-hookup, partial-hookup, and non-hookup loops, plus showers, a trailer dump, and a 60-foot limit.
Ike Kinswa State Park sits on Mayfield Lake near Silver Creek. The current campground map numbers 101 vehicle campsites: Loop A has full-hookup sites, Loop B has water-and-electric sites, and Loop D has non-hookup sites. Nine cabins are separate from that total. Washington State Parks lists showers, drinking water, a year-round trailer dump, and limited availability for equipment up to 60 feet. Loop B remains open year-round; Loop A and Loop D have seasonal closures, and Loop A hookups do not operate in winter.
Ike Kinswa State Park occupies forested shoreline on Mayfield Lake, a reservoir on the Cowlitz River. Boating, swimming, and fishing conditions vary with water level and season; consult current park alerts and fishing regulations before a visit.
Practical guidance assembled from current operator maps, park pages, and clearly identified community observations.
Riffe Lake waterfront sites (1–35) are the main draw — the lake is excellent for boating, waterskiing, and fishing. Hookup sites in Loop B are comfortable for longer stays. Mt Rainier is visible on clear days from the upper sites — a striking backdrop. Less well-known than coastal parks, making availability better on most summer weekends. A great family campground with lots of water activity options.
