Its convenient location provides access to all of the area's greatest recreation opportunities and lets campers relax and enjoy nature in the pine-covered mountains of Southern California.
Recreation
The campground provides access to a variety of hiking and mountain biking trails, including the Seven Oaks Trail, which is west of Big Bear Lake Village. The 30-year-old trail is overgrown in some areas, but leads to spectacular views of San Gorgonio Peak, the highest point in Southern California.
Fishing, boating and swimming at Big Bear Lake are popular activities. Anglers can look forward to trout, bluegill, crappie, catfish and largemouth bass, among other fish.

The campground offers one large group site for tent camping. It can accommodate up to 40 people and eight vehicles and is accessed by a dirt road. The site is equipped with picnic tables, grills and a campfire circle. Vault toilets are provided, but drinking water is not available and there are no trash collection services at the campground.
Natural Features
The group campground is located in the San Bernardino National Forest, south of Big Bear Lake. It is accessed via a dirt road, just off the main highway through the area. The campground is situated in a somewhat secluded stand of mature conifers, which provide much shade.
