The City of Twentynine Palms is the home of Joshua Tree National Park Headquarters and Main Park Entrance (aka the North Entrance) and proud host of the Marine Corps Air Ground Combat Center, the world's largest Marine Corps training base. The City is renowned for its world class murals and artists, supportive business climate, pristine air, beautiful natural surroundings, desert and mountain vistas, and friendly family lifestyle.   Beyond the last of the traffic lights, we are the gateway to the Mojave Desert, Joshua Tree National Park, the Mojave National Preserve, and the great California Outback. Enjoy our website, but we also invite you to experience the history, culture, lustrous starlit skies, breath-taking sunsets and sunrises in person.
