About Buttercup Group Camp
Overview
Buttercup Group Camp is an outdoor oasis nestled in Southern California's pine-covered mountains. Big Bear Lake is nearby, a popular destination for a variety of recreational activities. The campground offers a great escape from city life and it is one of the best locales for group camping.
Recreation
Fishing and boating at Big Bear Lake are popular activities. Anglers can look forward to trout, bluegill, crappie, catfish and largemouth bass, among other species. Because of the very cold water and the presence of underwater obstacles near the shoreline, swimming at the lake is sometimes discouraged.
Visitors also enjoy the area's plentiful hiking, mountain biking and climbing opportunities. The campground provides access to a number of trails and points of exploration.
Facilities
The group campground offers one large, accessible site that can accommodate up to 40 people and eight vehicles for tent or RV camping. The site is equipped with tables, grills and a campfire circle. Vault toilets and drinking water are provided.
Natural Features
The group campground is situated at an elevation of about 7,000 feet and is heavily forested with pine trees. The site is relatively shady and secluded. It is about two miles from Big Bear Lake and is accessed by a dirt road.
Getting there
From San Bernardino, take I-10 east to Running Springs. Turn onto State Highway 18 and continue to Big Bear Lake Dam. Continue about 6 miles on State Highway 18 and turn right on Summit Boulevard. Turn left at the end of road and go about a half-mile to the second gate on the right.
