Among the live oaks in southeastern San Diego County is Cottonwood Campground. The campground offers a tranquil and refreshing experience. Cottonwood Campground is an excellent starting point for day hikes, overnight backpacking trips, and equestrian use. The campground is located in the McCain Valley Resource Conservation Area. A trail out of the campground leads to the Sombrero Peak Area, Upper Bow Willow Canyon, and Anza-Borrego Desert State Park. The Pepperwood Trail and Sombrero Peak Trail are both rated moderate to strenuous. The trails are sandy in composition and meander through public, state, and private lands. Elevations range from 3,000 to 4,500 feet. This makes the area an excellent escape from the hot summer temperatures of lower elevations. Most precipitation is received from December through April. Thundershowers are common during July and August. Winter temperatures range from the 50s (F) to below freezing, with occasional snowfalls. Summer temperatures range from 60 to 95 degrees (F).Cottonwood Campground is a year-round facility with 25 developed campsites. Fire rings, tables, and vault toilets are found in the campground.
