The seven mile gravel track to Palm Canyon that branches east from US 95 across the edge of the wide, empty La Posa Plain is flat but rather bumpy, and the drive can take over half an hour. The canyon is the most visited location within Kofa National Wildlife Refuge, partly since it is the last place in the state where native California palm trees grow in their natural habitat. The last mile of the approach road climbs gradually and ends at a parking area, high enough to enjoy views over a huge area of the surrounding Sonoran Desert.
