Uniquely amongst Southwest preserves, Joshua Tree National Park
spans two deserts; the slightly cooler Mojave Desert in the western half and the lower, hotter Sonoran Desert to the east. Most facilities are in the west, as this is the region colonized by the distinctive Joshua tree - magnificent forests cover the plains and hillsides, mixed with piles of photogenic rounded boulders. Other prime attractions are six oases where California fan palm trees grow in their natural surroundings, all reachable by trail. The park has several campgrounds, set right amongst the trees and rocks, plus scenic drives and many hiking paths.
