Area Benefits

Twentynine Palms, including the Marine Base, has a population of about 25,000. The Marine Base is the City's northernmost neighborhood. Southwest travelers know this growing oasis in the Morongo Basin as a gateway to the scenic 558,000 acre Joshua Tree

National Park, and as a restful stopover on State Highway 62 between Los Angeles and the aquatic playground areas of the Colorado River. Reasonable land prices, clean air, modern conveniences, golf courses and parks, plus aviation facilities and pleasant year-round living conditions are among enticements that draw new residents to Twentynine Palms. Hot, arid summers and invigorating but mild winters in Twentynine Palms mark the location as a mecca for those seeking a healthful climate.
