Behind the Oasis visitors center in Twentynine Palms, this natural oasis encompasses the original 29 palm trees for which the town is named. They were planted by members of the Serrano tribe, who named this "the place of little springs and much grass." The Pinto Mountain Fault, a small branch of the San Andreas, runs through the oasis, as does a 0.5-mile, wheelchair-accessible nature trail with labeled desert plants.
