Green River Campground

Nice campground, mix of small and large campsites. You’re right on the river, but it’s fast moving and we didn’t see access for anything other than fishing. (Kids were disappointed in that) The dinosaur quarry exhibit hall is a must, everyone enjoyed it.
We came in late afternoon on a Saturday and there were several first come first serve sites to pick from. The campground almost filled up by the end of the night, though. When we arrived, there were not many sites left that would accommodate our 24” trailer and truck.
Lots of wildlife in the campground, squirrels and bunnies, even a few deer.
We had a good ATT signal, surprisingly.
The road down into the campground is very steep, but it’s not long.

Buried in the TripAdvisor reviews are enforced quiet hours for this campground. We didn't test it and ran CPAP with a car battery. Also dealt with water/sewer before and after, didn't use the campground facilities.

Was a quick stop. In at midnight, pulled "through" the pullout style site, didn't unhitch, levelled as quietly as possible, up early, walked to the river (not visible from the site). Then packed up and parked at the quarry visitor center for our shuttle Tix, hiked petroglyphs and fossil loop, home to Denver that night.

Site was the only reservation left for a Saturday night. Knew we'd be in late so it was a good call to have it waiting.September cooler, but still noseeum gnats were out in force.

Would like to explore the Colorado side of the park next time, hear good things.

FWIW, the switchbacks on 191 are the most doable route if you're coming from Idaho/Wyoming as we were. Still pretty exciting doing that dam in the dark.

Several of the sites are small there are plenty to accommodate bigger rigs. Most sites are fairly level and a little close together. There are some really good short hikes in the area, one of which is right out of the campground. We also found some 4-wheeling in the monument and the surrounding BLM property. It looks like you may need reservations on the weekend but it is pretty open during the week.

Green River offers a variety of large, level, and spacious campsites in a natural setting with beautiful surrounding views. This is an ideal location for what most people think of as camping with access to Dinosaur National Monument and the Green River is a minute walk from any of the campsites. Each campsite includes a fire pit/grill (off limits during the current fire ban) and picnic table, and the campground offers bathhouses and drinking water (skinny non-threaded spigots with low water pressure, not intended for filling RVs). There are no RV services (filling water, dump station, or electricity), and tree cover is more in some sites/less in others (great for cover on the hot days, not so great if you are hoping to use solar). Verizon service was very minimal (texting worked), and the booster did nothing to improve the situation. This is a pretty National Park and easily accessible to big-rigs, and we would stay here again, but we'd pre-plan our outings to work around the lack of internet service. It's also worth noting that since the campground is located within the National Monument, you'll need to pay the entrance fee or have an America The Beautiful park pass.

...if you're not concerned with long dirt roads or very large RV spots, there is simply so much better than this place.

If it were the only option, sure, it's pretty nice. But there's better river access at the other two campgrounds, there are less people, and the people who were camping here just weren't digging the "worldwide pandemic, be nice" or even "be nice" parts of camping which I consider essential.

I also blame the hosts and rangers, who did nothing to enforce safety precautions in the visitors center or the campground. So (sticks tongue out, takes ball, goes home), there.

Having gravitated toward free campsites lately, I’ve become pickier about paid sites. The $18/night rate reflects having access to running water and flush toilets, I believe. We were able to find an amazing shady spot that accommodated our two sleeping tents plus a shade tent over the picnic table that was close to the restroom and the river. If we had been in some of the less-shaded spots that were a longer walk to the restroom or the river, I might have been a little less approving of the $18 cost, but if you’re accustomed to paying upwards of $40/night at RV parks, the location and the larger, more private sites will make this feel like a bargain (but no dump site). Trash and recycling is provided. It was a great base camp for seeing Dinosaur NM.

There are a few options in Dinosaur and in Vernal for gas, restaurants, and supplies, but if you’re used to larger towns/cities, you’ll find the offerings limited, so don’t plan to eat most of your meals out, if that’s something you enjoy doing on a trip. My friend and I both use Verizon and our service varied a bit. We were generally able to send/receive text-based messages from the campground, but expect to have to drive to get better signal (but you may have better luck than I did).

The campground has a few different kinds of sites—some back-in and some “pull-up” (not really pull-through, but you can sidle your rig alongside some sites where the parking spot is a widening of the road, if that makes sense). Loop B is reservable online, but loops A and C are first-come, first-served.

While in the park, we explored some of the other campgrounds. Rainbow Park was absolutely horrible for mosquitoes (mid-June). We had a much better time at Green River Campground than we would have at Rainbow Park. We still went home with some bites, but nothing like Rainbow Park.

Green River Campground is about 6 miles from the entrance and Quarry Visitor’s Center on the Utah side of Dinosaur National Monument. The campground has three loops: A loop is first come/first serve and has fewer trees with more exposed spaces, catch the River Trail between sites A10 and A11; B loop allows reservations mid-May through mid-September and open spots are available for one night only; C loop is also first come/first serve, river access is easier and there are more trees/shade. All three loops are a mix of pull-through and back-in sites, each with a picnic table and fire ring.

There are bathrooms in each loop (flush toilets) and outdoor water spigots, but no showers. No dump station. Garbage dumpsters and recycling stations are next to the bathrooms.

We scored a pull-through site on the river side and loved it! Lovely views across the water and easy access to a sandy riverside place to sit or play. The river runs pretty fast and was chocolate brown from heavy rains during our stay. We visited the Colorado side of the park and checked out some of the boondocking spots off of Blue Mountain Road. We weren’t tempted to move. We also drove the 13 miles of dirt road to Echo Park campground. It’s worth the drive just for the fun of it, but certainly not appropriate for larger rigs or if you’re just looking for an overnight spot.

Green River is close to the absolutely not to be missed Fossil Quarry and this would be our pick for camping if we return.

We had 3 bars of Verizon 3G.

We arrived on a Saturday before noon in June and there were plenty of first come first serve spots available. The site was a pull-over to the side of the road style spot. There aren't any hookups but loop A has plenty of sun for solar.

We only had time to go to the visitor center and tour the Quarry Exhibit Hall (which is really cool). We also enjoyed the trail off of loop A which goes along the river.

We got a pullthru site that had our door facing the river. It was beautiful, but getting warm by late June. We had spent the previous nights boondocking just outside the Dinosaur National Monument on the Colorado side at about 7000', and found this boondocking to be crowded and hot. There was no respect for campsite - if someone wanted to go to the river, they walked between our motorhome and toad and through our site to get there.
It was nice to be able to see the dinosaur bones, and take the Desert Voices hike, the auto drive and see the pictographs, and to attend the ranger talk on bats.
