Oso Group

Oso Group is a national park campground at San Bernardino National Forest in San Bernardino County, California. Reservations are managed through Recreation.gov. When a booked site here is cancelled it can vanish within minutes, so Campsite Tonight monitors it 24/7 and auto-adds the opening to your Recreation.gov cart before anyone else.

Oso Group is in very high demand — sites here routinely sell out well in advance. Cancellations are often the best way in, which is exactly what Campsite Tonight watches for.
