Behind the park HQ and Oasis Visitor Center, this natural oasis encompasses the original 29 palm trees that gave Twentynine Palms its name. They were planted by native Serranos 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.
