Palomar Mountain State Park boasts 1,862 acres of peaceful meadows and lush oak and conifer forests. The area has a Mediterranean climate, meaning summer temperatures average around 80 degrees while winter temperatures can drop below 30 degrees. Spring and autumn tend to be more moderate. Wildflowers such as western dogwoods, azaleas, lilies, and lupine, dot the mountain with color each spring. Palomar Mountain has many bird species as well, such as bluebirds, woodpeckers, and hawks. Land animals include coyotes, bobcats, and southern mule deer.
The park is home to one of the highest peaks in San Diego County, at 6,140 feet. Because of the high elevation, lightening strikes are a very real danger, and they often cause wildfires in the area. The Boucher Hill Fire Lookout Tower was built in 1935 and has since been restored. It is open to park visitors when volunteers are available. There is also a nearby patio overlooking the Pauma Valley.
With plenty of trails such as the Silvercrest Trail, Palomar Mountain is a great spot for day hikes with rewarding views. The park is an excellent camping spot as well. The Doane Valley Campground is accessible and has 31 family sites, each sporting a table, fire ring, barbecue pit, and food locker. Restrooms and drinking water are available here. The Cedar Grove Campground is suitable for larger groups and those who have trailers or camper vans.
