About Green River Campground
Overview
The Green River Campground is located along the banks of the Green River at an elevation of 4,750 feet (1448 m). The highly eroded Split Mountain is visible to the north. 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 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.

FAQ
How do I get a reservation at Green River Campground?
Campsite Sniper's current snapshot shows none of the 237 tracked site-nights open for online reservation at Green River Campground. That can mean dates are reserved, closed, not yet released, or offered first-come, first-served rather than online. Campsite Sniper has also detected 101 site openings here in the last 90 days, so further dates may appear. Pick a site on the map to see its calendar, or set a free Campsite Sniper alert. You complete the reservation yourself on Recreation.gov.
Does Campsite Sniper book this campground for me?
No. Campsite Sniper sends alerts and direct Recreation.gov links. It never books, pays for, holds, hoards, or resells reservations.
How current is this availability data?
Campsite Sniper re-checks public Recreation.gov availability for this facility every hour and republishes whenever anything changes. This facility's data last changed at Nov 2, 2026 16:20 UTC; an older timestamp means nothing has changed since that time, not that checking stopped. Always confirm final availability on Recreation.gov when you book.
How often do new openings appear at Green River Campground?
Campsite Sniper detected 101 site-date openings here over the last 90 days, none in the last 7. A free alert watches around the clock and pings you the moment one appears.
Which sites at Green River Campground fit a 35-foot RV?
54 of the 79 sites that support RV analysis have a recorded maximum of 35 ft or more; the longest recorded is 75 ft.
When is the next open date at Green River Campground?
Campsite Sniper cannot answer that from the current snapshot. The availability data held for Green River Campground begins May 1, 2027 — about 180 days after this snapshot was taken, so any earlier dates are outside what Campsite Sniper is tracking here rather than known to be unavailable. Check Recreation.gov for dates before May 1, 2027.
