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. 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.
