Test Site is a climbing area in the Santa Monica Mountains National Recreation Area in California, managed by the National Park Service. It sits within the recreation area's land, and there is no fee to visit. Spring and fall are the most comfortable times to go. Typical averages from a nearby weather station show April highs around 78°F and November highs around 76°F, while July and August average in the mid-90s. That station sits well below the site, so temperatures here run cooler. Several climbing areas lie right next door, including Java Wall, Alcove, The, and Treasure Towers, all about 0.1 mile away. The Mishe Mokwa Trail is about 0.3 mile off, and Circle X Ranch Group Campground is about 1.2 miles away.
