About This Lake

Swimming Conditions

Lake Wilderness offers moderate water clarity with visibility typically ranging from 5 to 10 feet during summer months, though this can vary seasonally. Water temperatures average around 72 degrees Fahrenheit in peak summer, warming from cooler spring temperatures and cooling again in fall. The lake reaches depths of 40 feet in certain areas but provides shallow swimming zones suitable for beginners and children near designated beach areas. Swimming spots are concentrated along the developed shoreline near the main park facilities, where the bottom is generally sandy and gradually sloping. The lake's protected basin provides calm conditions most of the time, though occasional wind gusts can create small waves on exposed areas. Currents are minimal throughout most of the lake. Lifeguard presence is seasonal, typically available during summer months when usage peaks. Safety considerations include respecting depth markers and swimming within designated areas, particularly for families with young children.

Visitor Information

Lake Wilderness is located approximately 30 miles southeast of Seattle, accessible via Highway 18 and local roads through rural Pierce County. Free parking is available at the main park facility with space for approximately 150 vehicles, though this can fill during peak summer weekends. Facilities include restrooms, picnic areas, a small concession stand with seasonal operations, and a boat launch. The area has limited nearby dining options, with the closest restaurants and grocery stores in nearby communities. For overnight accommodations, visitors should consider nearby towns such as Enumclaw or Buckley, located 10-15 minutes away. The best time to visit is June through September when water temperatures are warmest and all facilities are fully operational. Spring and fall visits are possible but expect cooler water temperatures and variable weather. Winter access may be limited due to weather conditions. Bring sunscreen and plan to spend a full day enjoying the lake's recreational opportunities.
