Moses Lake Sand Dunes

Monday, November 09, 2015

Alt Names

Grant County ORV Area, Potholes Reservoir

Last Known StatusOpen

About 3,000 acres of rolling sand dunes are available here for motorized use. Camping is permitted but there are no facilities. Direct access to the lake makes this a choice spot so you can bring along the water toys too. Note that the dunes are covered with volcanic ash and tend to be little dusty.

New riders should note that this is a dune area so something like a Sand Snake paddle tire for motorcycles or Sedona Cyclones sand tires for ATVs may be helpful. Failure to use a sand tire in deep sand can sometimes result in unnecessary wear or damage to your vehicle.
