Cima Dome Joshua Tree Forest

Cima Dome rises like a gentle volcanic shield from the Mojave Desert floor, crowned by the world’s most spectacular Joshua tree forest. These ancient, twisted sentinels grow thicker here than anywhere else on earth — some specimens tower 40 feet tall and date back centuries. The dome itself is a geological marvel, formed by underground magma that never quite broke the surface, creating this broad, symmetrical rise that’s visible for miles across the desert.

Access the forest via Cima Road (paved) or Morning Star Mine Road (graded dirt) from I-15. The trees are most photogenic at sunrise and sunset when the light catches their spiky silhouettes. Spring brings a brief wildflower bloom if winter rains cooperate. No facilities here — this is raw desert country where you bring everything you need.
