Lost Palms Oasis is located in the southeastern portion of Joshua Tree National Park. This oasis can be reached on a 7.5 mile out and back hike from Cottonwood Spring with 500 feet of elevation gain. The trail is on a mix of rock, dirt, and sandy washes with very little shade and includes a strenuous climb on rocky terrain out of the canyon that the oasis is located in at the far end of the trail. The oasis is located in Lost Palms Canyon where a permanent water source allows fan palms and other plants to thrive, supporting a vibrant desert wildlife community.
