Oso Group Campground

Group camping takes center stage at this US Forest Service site in San Bernardino National Forest, where a single reservation accommodates up to 100 people for $480-$490 per night. The campground sits in forested terrain near both river and lake access, though campers should prepare for rough road conditions leading to the site. RVs up to 40 feet can navigate the space, and both campfires and pets are permitted within the established boundaries.

Fishing opportunities draw visitors to the nearby water features, while the open terrain sections provide flexibility for large group setups. For those planning smaller gatherings, campgrounds around Big Bear Lake offer additional options. Reservations are available and recommended given the specialized group format and limited availability.
