About
Overview
Rainbow Park Campground is 28 miles (45 km) from the Quarry Visitor Center in the Utah portion of Dinosaur National Monument. It is located on a rugged dirt road that is impassable when wet. The campground sits beside the Green River near the Rainbow Park Boat Ramp at the head of Split Mountain Canyon. Rainbow Park Campground is open year-round, but there is no winter maintenance on the unpaved road.
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 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.

Is Rainbow Park Campground fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.

We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification — and on Recreation.gov we can put the site straight into your cart, so it is held while you get to your phone.
