The Split Mountain Group Campground is located along the banks of the Green River at an elevation of 4,800 feet. The highly eroded Split Mountain towers over the campground.
The campground is near the famous dinosaur quarry, where you can see 149 million year old dinosaur bones still encased in the rock. Adjacent to the campground is the Split Mountain Boat Ramp where river rafters come off the Green River after trips through Dinosaur National Monument's canyons.
The campground offers four group sites that accommodate both tents and recreational vehicles. Each campsite has a picnic table, campfire ring with grill and can accommodate up to 25 people and six vehicles. Drinking water and flush toilets are available from early April to early October. However, no water, sewer or electric hookups are available for recreational vehicles.
Due to a construction project, the Split Mountain Group Campground will be closed from May 31st to June 21st.
All campers must pay the monument's entrance fee in addition to the fees for camping. Entrance Passes can be purchased at the monument's entrance station or visitor center. Valid National Park passes are also accepted.
CAUTION: Dinosaur National Monument is home to black bears along with many other animals. Proper food storage is required in campgrounds, picnic areas and while backcountry camping.
Summers are hot with daytime high temperatures often exceeding 100 degrees. Winters can be cold and snowy.
During the off-season (approximately the first week of October to early April--subject to change depending on local weather and other factors), Split Mountain Campground serves as a general campground. There is no water, but a vault toilet is available. There are no reservations at Split Mountain during the off-season.
There are no dump stations or electrical hookups at Split Mountain Campground. Generator use is prohibited from 9 p.m. to 7 a.m.
Don't Move Firewood: Help protect our forests! Prevent the spread of tree-killing pests by obtaining firewood at or near your destination and burning it on-site. Moving firewood is illegal in some states. Visit dontmovefirewood.org to learn more. Firewood is for sale in Split Mountain Campground.
Dinosaur National Monument has a separate entrance fee. Campground reservations do not cover entrance fees.
The campground is set on a bench along the Green River and is dotted by Fremont Cottonwood and sagebrush. Campsites offer views of Split Mountain. Limited shade is provided by the few trees in the campground.
In addition to the monument, nearby Utah State Parks, the Ashley National Forest, Flaming Gorge National Recreational Area and Bureau of Land Management sites provide additional recreational opportunities in the area.
Dinosaur National Monument covers over 210,000 acres. The monument features two visitor centers, the Canyon Visitor Center in Colorado and the Quarry Visitor Center in Utah. On the Utah side, experience the Quarry Exhibit Hall, where you can view over 1,500 dinosaur fossils still in the rock.
Throughout the monument, several roads provide access to key destinations and scenic sites. There are miles of trails for hiking and cross-country travel. Whitewater rafting (permit required) is popular on the Green and Yampa Rivers. Numerous cultural sites reveal stories of the people who lived here before and include Fremont petroglyphs, homestead cabins and former ranches. Scenic drives allow visitors to see the spectacular geology in the area.
