Dinosaur River Expeditions is a family-owned, locally operated whitewater rafting outfitter based in Vernal, Utah. The company runs guided trips on the Green and Yampa rivers, taking visitors through the dramatic canyons of northeastern Utah, Colorado, and Dinosaur National Monument. Its adventures include one-day Green River outings, multi-day trips through Flaming Gorge and the Gates of Lodore, and Yampa River expeditions, with options for custom trips. The Green River offers trout water and Class II–III rapids, while the free-flowing Yampa joins the Green at Echo Park within Dinosaur National Monument.

Experienced guides lead each journey and manage practical details such as permits, equipment, meals, and camps, allowing guests to focus on the river and surrounding scenery. The outfitter also provides trip information, reservation support, and resources about the Vernal area, including its outdoor recreation and local attractions. Dinosaur River Expeditions is an authorized concessionaire of Dinosaur National Monument, the Bureau of Land Management, and the Forest Service.
