The Oso Group Campground is nestled in the beautiful Barton Flats area of the San Bernardino Mountains. It is surrounded by picturesque pine trees and miles of scenic landscape. In addition to a nearby lake and river access, a variety hiking, biking and horseback riding trails can be accessed from the campground. Its location also provides a great place for visitors to relax, take in the fresh mountain air, and enjoy the beautiful scenery. The group campground offers one large group campsite, available for tent and RV camping. It can accommodate up to 100 people and about 20 vehicles. There are no utility hookups at the site and roads, as well as the parking area, are gravel and dirt. The site is equipped with multiple tables, a campfire circle and grills. Flush toilets and drinking water are provided at the campground. Tent pads are shaded but group areas are primarily in the open. The campground is located in a dense pine forest, at an elevation of about 6,400 feet. The entrance to the Oso Group Campground is the same as for the neighboring Lobo Group Campground. Both share the region with a variety of wildlife and bird species. The Grayback Amphitheater on State Route 38 provides evening educational programs on most Saturdays and Sundays throughout the summer months. Programs are hosted by the San Gorgonio Wilderness Association and pertain to the area's background that is rich with history. The campground provides access to the famed Santa Ana River Trail, which when completed will travel all the way from the mountains to the pacific ocean, providing spectacular views along the way. It is currently popular for hiking, biking and horseback riding. The Rio Monte Trail is also accessed from the campground, taking hikers to the Rio Monte Panorama, which overlooks the deep gorge of the Santa Ana River Valley. Visitors can also enjoy fishing and non-motorized boating at the nearby Jenks Lake, a small mountain lake with a picnic area and access to hiking trails. The lake is stocked with rainbow trout, as well as largemouth bass, bluegill, sunfish and catfish. Rowboats, canoes and kayaks are permitted and fishing is also available at the nearby Santa Ana River.
CampFinder checks Recreation.gov every 30 minutes, around the clock, and emails you when a booked-up night opens back up. That catches most cancellations, which sit open for hours; at the few campgrounds that refill in seconds it can miss the race. Set up a free availability alert for OSO GROUP.
