Sand Wash serves as the primary launch point for the 84-mile Desolation/Gray Canyons float trip on the Green River, featuring a primitive boat ramp, staffed ranger station, eight campsites, and four screened cabins (12'x16' with table and bench) to protect from frequent mosquito plagues.

The remote location requires traveling graded gravel roads from Myton or Duchesne with limited cell coverage, and offers vault toilets but no water or trash services—visitors must be completely self-sufficient.

A permit is required year-round for river trips, and the site is ideal for groups planning multi-day river expeditions through scenic canyons with Class II-III whitewater.
