Explore the Bentonite Hills at Sunset

ScenicEasySpringYear-round

Watch the otherworldly blue and purple mounds near Cathedral Valley transform into a psychedelic landscape as the light fades.

Itinerary tips

  • 1Plan for at least a two-hour round trip from Torrey, accounting for slow speeds on the unpaved Hartnet Road.
  • 2Bring a high-clearance 4WD vehicle to navigate the sandy washes and potential mud along the Cathedral Valley loop.
  • 3Pack a high-powered headlamp or flashlight for the trek back to your vehicle, as the desert becomes pitch black immediately after the sun drops.
  • 4Download offline GPS maps before heading out, as cellular service is non-existent once you leave the highway.
  • 5Check the weather forecast at the visitor center for flash flood warnings, as the bentonite clay becomes impassable when wet.
  • 6Park in designated pull-offs along the road to avoid damaging the fragile biological soil crust surrounding the mounds.
