Dark Sky Locations Near Los Angeles

Drive east toward Joshua Tree or north toward the Mojave for the fastest dark sky from LA. The San Gabriels are close but the light dome from the LA Basin illuminates them significantly — you need to get over the ridge and into the high desert. Each location links to a live StarCast forecast — click any to check current moon phase, cloud cover, and transparency before you drive.

Before you go

Check Conditions, Not Just Location

Location is only half the decision. Moon phase, atmospheric transparency, and cloud cover on the specific night determine whether the drive is worth it. A Bortle 2 location on a full moon night is worse than a Bortle 4 location on a new moon with excellent transparency. Check StarCast for your target location before leaving — not just the general weather forecast.
