What to do in Moses Lake State Park

Moses Lake State Park offers 77 picnic sites, two picnic shelters, a vault toilet, a bathhouse, an unguarded swimming beach, and a 2-lane boat launch. The park covers 78 acres with 862 feet of freshwater shoreline on Moses Lake. The Commission has a concession agreement for the sale of food and beverages.

Activities include boating, fishing, ice skating, picnicking, scuba diving, swimming, and water skiing.

Moses Lake State Park, in south central Washington, is located in Grant County, five miles west of downtown Moses Lake, off Interstate 90.

The climate of Washington varies within each region. The Cascades split the state and alter the weather patterns. The terrain east of the mountains, which includes Moses Lake State Park, receives approximately 12 inches of rainfall per year, generally much less than west of the mountains. Since the area east of the mountains is landlocked, temperatures in this region are lower during the winter months. Frequent winds coming down from the mountains also contribute to the low temperatures of eastern Washington.
