In the agency’s own words

The Split Mountain Group Campground is located along the banks of the Green River at an elevation of 4,800 feet. The highly eroded Split Mountain towers over the campground. The campground is near the Quarry Exhibit Hall, where you can see 149 million year old dinosaur bones still encased in the rock. Adjacent to the campground is the Split Mountain Boat Ramp where river rafters come off the Green River after trips through Dinosaur National Monument's canyons. Keep reading

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.

Facilities

The campground offers four group sites that accommodate both tents and recreational vehicles. Each campsite has a picnic table, campfire ring with grill and can accommodate up to 25 people and six vehicles. Drinking water and flush toilets are available from early April to early October. However, no water, sewer or electric hookups are available for recreational vehicles. RVs can not fill their potable water tanks at the campground.

Natural Features

The campground is set on a bench along the Green River and is dotted by Fremont Cottonwood and sagebrush. Campsites offer views of Split Mountain. Limited shade is provided by the few trees in the campground.

Nearby Attractions

In addition to the monument, nearby Utah State Parks, the Ashley National Forest, Flaming Gorge National Recreational Area and Bureau of Land Management sites provide additional recreational opportunities in the area.

Nothing on the booking system for the next 30 nightsread 16:54 UTC

recreation.gov lists 4 of the 5 campsites the agency files here. The rest aren’t on its booking system, so a reservation won’t get you one.

Every one of the next thirty nights is in recreation.gov’s record and not one site is being offered on any of them. That’s a campground closed or not yet released for booking, not a sold-out one.

Who keeps the booking fee

The agency’s own policy text says the reservation fee and the cancellation processing fee are “retained by the reservation service contractor”, and that a campground concessionaire will decline to refund them because “they did not receive these fees”. Recreation.gov is run under contract by Booz Allen Hamilton. What share of your booking fee the contractor keeps isn’t published in any federal dataset we can read, so we print no number for it.

How we know

every fact on this page, and where it came from
Right now: National Park Service publishes no season and no closure for this campground, and it takes no bookings we can read. That’s a gap in the record and not a locked gate: the number below is the only way to be sure.
Cell signal: the Park Service’s own campground description, read as text by CAMPANAC. None of this is a measurement. It’s what the land manager published about the place, and phones, carriers and weather all disagree with each other; treat it as a warning, not a promise.
Nearest place of any size: Jensen, UT, 5.9 mi NE (a census designated place). Straight line.
