How dark is it, really?

Dark enough to see the Milky Way overhead on a clear night, though glow from nearby towns washes out the sky near the horizon. (For the detail-minded: Bortle class 4, an estimate.)

When should I go?

Pick a night when the moon is down. The next stretch of moonless evenings is Nov 6–12.

What it's like

Anza-Borrego is California's largest state park, a two-hour drive from San Diego, with 12 wilderness areas, 500 miles of dirt roads, and about 110 miles of hiking trails across the Colorado Desert. The rugged ground and hard climate have kept the southern California desert largely undeveloped, and that keeps its night sky relatively dark. It became an International Dark Sky Park in 2018.

The town of Borrego Springs sits in the middle of the park, and it matters to the sky here. It is the biggest source of artificial light in the area, and in 2009 it became the world's second International Dark Sky Community, which helps protect the park around it.

Camping is the easiest way to stay under the sky. Sites are reservable up to six months ahead for October 1 to April 30, and camping fees include entry for one vehicle. In the campgrounds, quiet hours run 10 pm to 6 am, and anyone not staying the night must leave by 10 pm. From June through September the visitor center is open only Friday to Sunday, and some campgrounds, including Tamarisk Grove, close. By day, look for bighorn sheep, wildflowers, palm groves, and cacti.

Food, fuel, and supplies
