Observatory Campground is located in the Cleveland forest on Palomar mountain, and shares the same night skies as Palomar Observatory, just 2 miles away.  The site features the Explore the Stars program, presented by local amateur astronomers, a series of monthly two night star parties in spring, summer, and fall.

Borrego Springs, a desert community embedded within Anza Borrego Desert State Park, was designated a Dark Sky Community in 2009.  Situated on the desert floor, the town is protected from city light by the surrounding mountains.

Nightfall Star Party & Imaging Conference is hosted by the Riverside Astronomical Society under the clear autumn skies over Anza Borrego Desert.  Established in 1993, the three night event takes place at a desert resort that maintains a red-light-only environment in the hotel and RV park.
