San Rafael Canyon, UT This remote BLM Recreation Area is in the canyon country of central Utah, straddling I-70. On the canyon's rim, where we chose to camp, dispersed camping is the rule. Some areas are closed to camping and are so posted. This site at the canyon's edge was not. From this point, the canyon drops 1,000 feet to the San Rafael River. It is every bit as scenic as our famous Grand Canyon of Arizona.
