Calico Hills to Teutonia Peak — Mojave National Preserve Desert Crest Road

The Mojave National Preserve doesn’t advertise itself, and that’s exactly the point. Kelbaker Road drops you into the basin near Kelso Dunes — the tallest sand dunes in California outside of Death Valley — then the route pushes northeast through Cima Dome, a massive granite batholith so gradual you won’t realize you’re climbing it until the Joshua trees thicken around 5,000 feet. Teutonia Peak trailhead serves as a natural waypoint before the track cuts back down through old ranching roads and the ghost infrastructure of mid-century mining operations. Black Tank Road and Cedar Canyon Road are your connectors — both graded dirt, both exposed to full desert sun with zero shade.

This is legitimately a high-clearance 2WD route in dry conditions, but after winter rains the clay sections turn greasy and a 4WD with all-terrain tires earns its keep. Stock up on water in Baker or Needles — there is nothing inside the preserve. No permit required, dispersed camping is allowed throughout. Best window is October through April; summer temps routinely crack 110°F at low elevation. Cell service is nonexistent past Kelso Depot. The Depot itself is worth the stop — restored by the National Park Service and occasionally staffed.
