National Park Service · Utah
150 million years ago, dinosaurs roamed here. Their fossils are still embedded in the rocks. Today, mountains, desert, and rivers flowing in canyons support a variety of life.
Reservations for Dinosaur National Monument are made through Recreation.gov. In peak season, the most popular campgrounds are typically claimed within minutes of each release — which is why the park reads as "sold out" for most of the year.
Sold out is not final, though. People book far ahead and plans change, so cancellations return to the official calendar throughout the season — with no announcement, at any hour. A cancelled site is bookable by whoever sees it first.
