This site is pretty central in the whole Dinosaur National Park geography about an hour from the main visitor center. We definitely needed a high clearance vehicle for the dirt road to get to it but evidently the road conditions vary a bit season to season and year to year, so call the rangers to check. This is tent-only no reservations and there are water, toilets, and designated camp sites, making it a remote frontcountry style campground. I’m not sure where you could go instead if it fills up since it’s in the middle of the park, but it was only 3/4 or so full in early spring. The absolutely beautiful cliffs and water make this campsite memorable and the other nearby areas in Dinosaur (petroglyphs, cave, fossils) make it exceptional.
