Desolation Canyon Route Map: Sand Wash to Swasey's
Sand Wash to Swasey's Beach on the Green River, mapped from BLM and Recreation.gov facility coordinates.
Desolation and Gray Canyons run through one of the deepest canyon systems in the Lower 48 with over sixty rapids and riffles. BLM publishes coordinates for the launch and the take-out but not for the individual rapids and camps, so only the endpoints are pinned here. Camp assignments and rapid locations come with your permit packet and the BLM river map.
Access points and landmarks
An 84-mile trip from Sand Wash to Swasey's Boat Ramp, averaging 6 to 7 days for private boaters. Every coordinate below links to the published source it came from. Recheck access, closures, and water levels with the managing agency before you launch.

What we deliberately left off
- Nine Mile Creek, Rock Creek Ranch, Rattlesnake Rapid and Wire Fence Rapid — named in outfitter literature but without BLM-published coordinates, so they are not pinned.
