About

Overview

The Green River Campground is located along the banks of the Green River at an elevation of 4,750 feet (1448 m). The highly eroded Split Mountain is visible to the north. The campground is about five miles (8 km) from the famous Quarry Exhibit Hall, where you can see 149 million year old dinosaur bones still encased in the rock. A short distance from 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 Green River multi-day rafting trips start at Gates of Lodore. and the run to Echo Park is 19 miles. 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.
