About Green River Campground

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.

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.
