About this trail
Moses Lake's sand dunes offer rolling sandy terrain for off-road vehicles along the lake's southern edge. The map marks the county-published west access on South Sand Dunes Road. The adjoining Yellow Zone mud flats close annually from October 1 through June 30; stay within areas currently open to riding. Follow county requirements for vehicle registration, safety equipment and visible dune flags. Holiday weekends bring additional camping restrictions to keep emergency routes clear. Check current county notices, changing sand conditions and posted boundaries before visiting.
