Green River Rafting in Jensen, Utah

One-day Split Mountain Gorge

Experience Utah rafting at its best on a one-day Green River rafting adventure through the Split Mountain Gorge. Visit the land of dinosaurs, wild geologic folding and colorful canyon history in Dinosaur National Monument. Challenge class III rapids like Moonshine, S.O.B., Schoolboy and Englesby – first encountered and named by the famous explorer John Wesley Powell.

Paddle or Row?

Trips are usually run in paddle rafts (everyone paddles), but oar boats (you do not have to paddle) can be requested. Both options hold five to eight people plus a guide.


Raft Split Mountain Gorge on the Green River

Adrift Adventures explores the Split Mountain Gorge by raft each day throughout the summer. Trips depart at 9:00 am and are limited to 25 people. On the shuttle to the river you will stop to view Native American rock art left by the Fremont People approximately 1,000 years ago. After a safety orientation at the put-in you will float nine miles on the Green River, where you will encounter multiple class III rapids. Stop at a sandy beach half-way through the trip where guides prepare lunch. More rapids and exploration fill the second half of the trip with an approximate return time of 3:00 pm.
