Dark Sky Spots: Cap Rock to Pinto Basin

Night skies are a major draw here, since the park is an International Dark Sky Park and one of the finest national parks for watching the stars and capturing the Milky Way on camera.

Dark Sky Spots: Cap Rock to Pinto Basin, Joshua Tree National Park

On a clear night with no moon, stars are visible from anywhere in the park. Light from surrounding communities does reach some areas more than others, so the spot you choose matters.

Four designated stargazing areas sit in the parking lots at Quail Springs, Hidden Valley, Cap Rock, and Ryan Mountain. By day, Hidden Valley makes a quick outing: its one-mile loop winds through a small valley ringed by piles of boulders and rocky walls, with a picnic area nearby. Ryan Mountain asks much more of hikers. The round trip covers three miles with roughly 1,050 feet of climbing and no shade, so skip it when the weather is hot.

Pinto Basin Road runs from White Tank to the south entrance, and the sky above it is among the darkest in the park. Pull over at any turnout along it, but keep within 20 feet of your car. Cholla Cactus Garden is another good option, as it sits a considerable distance from the nearest towns.

Plan ahead. A red-tinted flashlight keeps your night vision intact, and your eyes need about 20 to 30 minutes to adapt to the dark. Keep an eye on the forecast, because cloud cover hides the stars and evenings here can turn much chillier than the afternoon. Moonlight matters too, since a bright full moon hides many stars, which makes a moonless night the best choice.

  • Where Mojave Meets Colorado Desert

    Two desert ecosystems meet in this park, the Mojave and the Colorado, and elevation is the main factor separating them.

  • Bighorn Sheep, Coyotes and Desert Survivors

    Desert bighorn sheep are one of the park's notable animals. To let them reach water sources without being disturbed, certain areas are off limits to overnight stays.

  • Keys Ranch and Bill Keys' Desert Homestead

    Keys Ranch can only be seen on a ranger-led walking tour. Park staff limit access to guided walks to protect the property's historic character, and each outing covers about half a mile and lasts between 90 and 120 minutes.

  • Nine Campgrounds and Peak-Season Camping

    Joshua Tree National Park has nine campgrounds, with settings that range from developed sites with full facilities to more primitive camps.
