Mojave Trails National Monument protects a staggering 1.6 million acres of Mojave Desert between Barstow and Needles. The landscape stitches together ancient lava flows, shifting sand dunes, stark mountain ranges, and the longest remaining undeveloped stretch of historic Route 66. Shielded from city lights, the monument offers exceptional stargazing and a profound sense of solitude. Visitors come to trace the old highway, wander among lava flows and sand dunes, and experience a desert wilderness that feels unchanged by time.
Best season — Fall through spring, when daytime temperatures are mild and nights are crisp; summer often brings extreme desert heat that limits outdoor activity.
