Sand Dunes Access provides direct access to Potholes Reservoir with a boat ramp for water recreation, located adjacent to approximately 3,000 acres of year-round sand dunes open for motorized use.

The area offers vault toilet facilities and allows camping anywhere on the grounds, though no other services are available, so visitors should bring their own water and shade.

A staging area and multiple boat ramp locations (including Montlake Park Boat Ramp) serve as entry points for both water activities and off-road vehicle recreation.
