Overview of Palomar Mountain Camping

Palomar Mountain offers camping, hiking, stargazing, and other outdoor adventures in a rugged alpine landscape that contrasts starkly with the Mediterranean climate found at lower altitudes nearby.

The area comprises Palomar Mountain State Park, managed by California State Parks, as well portions of Cleveland National Forest, managed by the United States Forest Service. Two of the area’s campgrounds are managed by California State Parks and three by the U.S. Forest Service.

Palomar Mountain camping conditions can change rapidly due to the elevation activity. Weather is a serious consideration on Palomar Mountain, and it’s important to be prepared, especially in the winter months, when nighttime temperatures often dip below zero and serious snowstorms can drop significant amounts of snow.

It’s a good idea to check whether the roads are open during and after snowstorms, as the authorities sometimes close the road or require that vehicles have chains. The San Diego Department of Public Works posts updates on conditions on Twitter and Facebook.

There are a few hotels and AirBnBs/VRBOs rentals available on the mountain, for those looking for an alternative to camping.

Getting to Palomar Mountain
Palomar Mountain is located in northern San Diego County, with portions in Riverside County. It is about an hour and a half drive from San Diego or Irvine. From the west, take Interstate 15 exit 46 at Pala Mesa and head east on Highway 76 for 21 miles. Turn left onto S Grade Road/Palomar Mountain Road, and climb the curvy mountain road for about 7 miles until it intersects with State Park Road. Crestline Group Campground is straight across the intersection. Check with San Diego Public Works on Facebook or Twitter for road conditions and restrictions.

The campground features 31 campsites that must be reserved through or calling 1-800-444-7275 during the peak season. During the winter months, campsites are first-come, first-served. One hike-in primitive campsite is also available at Doane Valley.

Doane Valley Campground Map

The campground is divided into two loops, with the loop containing sites 1-8 being the most level. There are two bathroom facilities with flush toilets and a shower facility. Each campsite has a picnic table and fire ring, and most have food lockers to protect your food from animals. Most of the sites have a maximum occupancy of eight people and two cars.

RV and trailer camping is permitted, but the park service discourages anything over 27 feet long due to the narrow and curvy road to the campground. Some of the campsites can only handle smaller RVs and trailers, so check the site details on the reservation website to make sure you’ll fit.

Engine-driven electric generators may be operated only between the hours of 10 a.m. and 8 p.m.

Collecting downed wood or other natural debris for fires is prohibited, as biomass is important for the local ecosystem. Firewood can be purchased from the camp host. During periods of high fire danger, campfires may be prohibited.

Things to Do on Palomar Mountain


Palomar Mountain is covered by a network of trails, with the epicenter of the network within Palomar Mountain State Park. California State Parks offers a map of hiking in the state park on its website.

Doane Pond is one of the highlights of Palomar Mountain State Park.

Doane Valley and Doane Pond are arguably the crown jewels of the area. Doane Valley Nature Trail, a short interpretive trail that runs along Doane Creek, is a great first hike if you’re looking for something low-key. The trailhead is located at the western end of Doane Pond Day Use Parking area (GPS: 33.342018, -116.901389).

Palomar Mountain Hiking Trail
Doane Valley Nature Trail is a short hike through a forest of tall trees that’s unusual for Southern California.

Several other trails have trailheads at the pond parking lot, including Thunder Spring Trail and Cedar Trail/Scott’s Cabin Trail and Weir Trail, which splits off from the nature trail.

Observatory Trail, in the national forest, is another popular hike. The trail starts at Observatory Campground and climbs 700 feet over 2.2 miles to end just outside of Palomar Observatory. Walk about a third of a mile to the Observatory for a visit (see below).

Another worthwhile activity is visiting Boucher Hill Overlook and Fire Tower, which can be accessed via care or by Boucher Hill Loop Trail.


Palomar Mountain Camping Sky

Palomar Mountain is home to Caltech’s Palomar Observatory for a reason. This is a premier stargazing location and on any given night you’ll find people in campgrounds peering through telescopes at the night sky.

Explore the Stars, an amateur astronomy project, takes place at Observatory Campground on several weekends each summer. A group of amateur astronomers from all across Southern California hold Star Parties to share the beauty and awe of the night sky with non-astronomers at the campground. Visitors can also walk a 2.25-mile trail to the observatory.

Visit Palomar Observatory

The observatory, atop Palomar Mountain, boasts five high-tech telescopes, among them, the massive 200-inch Hale Telescope, was the world’s largest effective telescope for about 45 years. The observatory is owned by the California Institute of Technology and astronomical research includes near-Earth asteroids and the study of distant galaxies.

With some exceptions, such as holidays and during winter weather, the observatory is open to the public daily, from 9 am to 3:30 pm. The observatory has a museum and offers guided tours spring through fall. For more information, visit the observatory website.
