Overview

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 Quarry Exhibit Hall, 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.

Recreation

Dinosaur National Monument covers over 210,000 acres (84984 ha).

Visitor Centers. The monument features two visitor centers - one in Colorado and one in Utah.

Quarry Exhibit Hall. You can see over 1,500 dinosaur fossils still in the rock inside the Quarry Exhibit Hall (Jensen, Utah).

History & Culture. Numerous cultural sites reveal stories of the people who lived here before and include Fremont petroglyphs, homestead cabins and former ranches. Hiking trails allow in-depth exploration.

Hiking . There are miles of trails for hiking and cross-country travel.

River Rafting & Boating. Whitewater rafting, both commercial and private, is popular on the Green and Yampa Rivers. The Yampa River multi-day rafting trips begin at Deerlodge Park. The Yampa rushes downstream 44 miles (71 km) to join the Green River at Echo Park. Boaters continue downstream on the Green River to the take-out at the Split Mountain boat ramp. The Yampa is the largest free-flowing tributary within the Colorado River system. As such, it has a shorter season marked by fluctuations in water level resulting from snow received in the winter. It is characterized by famous rapids such as Teepee, Big Joe and Warm Springs. Raft trips must be arranged in advance. For more information, visit Dinosaur's Commercial Guided River Trips page. Private River Trips require a permit.

Scenic Drives. Several roads provide access to key destinations and scenic sites. Scenic drives allow the windshield visitor to see spectacular geology.

Facilities

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. RVs can not fill their potable water tanks at the campground.

Natural Features

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.

Nearby Attractions

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.
