Boating and water recreation drive most visits to Mayfield Lake Park, a utility-managed campground on the shore of Mayfield Lake near campgrounds near Mossyrock. The lower loop sites sit directly on the water, and campers who reserve a lakefront spot can beach a boat right in front of their site. The campground includes a boat launch, ample parking for trailers, a swim area, and a playground, making it a functional base for families arriving by water or by road.
Every site has water and electric hookups, and sewer connections are available as well, with a maximum RV length of 100 feet. The terrain is open, meaning privacy between sites is limited, and reviewers consistently note that close site spacing becomes more noticeable as the campground fills during peak summer weekends. Highway 12 is audible from some upper loop sites at night. Tent campers should plan accordingly: the gravel surface throughout the campground makes sleeping pads and cots a practical necessity rather than a preference.
Cleanliness stands out across multiple reviews. Showers are coin-operated and consistently described as well-maintained, and the camp host staff receives repeated positive mentions. Trout fishing draws some anglers out on the water, though bank fishing has produced mixed results. Ike Kinswa sits about a mile to the east for campers weighing nearby alternatives. The campground runs from April 15 through October 15, with reservations available. Early season visits, when the site is less crowded and the weather cooperates, tend to give campers the most room to settle in.
