Sites 6, 7, and 9 – 16 have short walk-ins that give campers a bit more wilderness immersion.

Observatory Campground lies in a mountain forest of oaks and pines an elevation of 4,875 feet, 700 feet below Palomar Observatory. Trees have been cleared from much of the campground, affording campers with a clear sky view. Since Palomar Mountain is a place for astronomy enthusiasts, many of the campsites have cement slabs perfect for setting up a telescope to gaze up into outer space. Even without a telescope, you can enjoy a view of the night sky with minimal light pollution. According to the Cleveland National Forest webpage for Observatory Campground:

An exciting amateur astronomy project, called Explore the Stars – Star Parties, occurs monthly during the spring, summer, and fall at Observatory Campground. A group of amateur astronomers from across Southern California bring the beauty and the awe of the night sky to more than a hundred non-astronomers at a location only two miles from the world renowned Palomar Observatory.

Visit the Explore the Stars – Star Parties webpage or call the Palomar Ranger District of the Cleveland National Forest for more information, (760) 788-0250.
