83.0 miles: 1 hours, 22 minutes
Ride past Texas ranchlands, where deer and cattle graze on grass and scrub brush. Bitter Well Mountain and the Black Mountains create ridges on either side. Pass the Sierra Diablo Wildlife Management Area, home to bighorn sheep. See swirling white salt basin dunes in the north near Guadalupe Mountains National Park. There are no gas stations on the route, so fuel up in Van Horn.
