What campers say

Observatory Campground on Palomar Mountain offers a simple, well-located camping experience with flush toilets, water spigots, picnic tables and parking at most sites. It’s popular with amateur astronomers and has trails leading to the Palomar Observatory, making it strong for stargazing and short hikes. Sites vary: some are shaded and forested while others are open and hot in summer. Several visitors note insects (mosquitoes/flies) and occasional maintenance issues with showers/restrooms, so expect varying conditions. The winding drive up and limited premium sites mean booking ahead is recommended, though some walk-in sites exist.

📖 About This Campground

Science buffs and families are drawn to Observatory Campground for its proximity to the Palomar Observatory, a world-class center of astronomy research operated by the California Institute of Technology. Just two miles from the observatory, the campground provides visitors with a unique learning experience in the great outdoors. The facility offers a variety of amenities for both tent and RV camping. Hiking, biking and picnicking can be found nearby. The campground is organized around one large loop with parking spurs for each campsite. Several sites are equipped with level cement pads to allow campers to set up their telescopes. The sites can accommodate vehicles up to 32 feet in length. Drinking water, coin-operated showers (peak season only), grills, trash cans, campfire rings, picnic tables, a flush toilet (peak season only) and two vault toilets are provided. An exciting amateur astronomy project, Explore the Stars, occurs at the campground on several weekends each summer. A group of amateur astronomers from all across Southern California shares the beauty and awe of the night sky to more than a hundred non-astronomers at the campground. Visitors can also walk a 2.25-mile trail to the observatory itself. Day hiking, biking, picnicking and scenic driving are available in the area. The campground makes a good base camp for visiting Palomar Mountain State Park and exploring the surrounding forest.
