Dinosaurs once roamed here. Their fantastic remains are still visibly embedded in the rocks. Today, the mountains, desert, and untamed rivers flowing in deep canyons support an array of life. Petroglyphs hint at earlier cultures. Later, homesteaders and outlaws found refuge here. Whether your passion is science, adventure, history or scenery, Dinosaur offers much to explore.

Colorado is a big state, so it's only fitting that it was once home to the biggest of all dinosaurs. A huge number of sauropods have been discovered in Colorado, ranging from the familiar Apatosaurus, Brachiosaurus, and Diplodocus to the less-well-known and harder-to-pronounce Haplocanthosaurus and Amphicoelias.

Take on gargantuan fossil tracks at Picketwire Canyonlands south of La Junta, Colorado. Here, visitors can feast their eyes on the nation’s largest collection of fossilized dinosaur footprints, as well as put their own tiny feet right inside them. The area boasts nearly 1,300 dinosaur tracks from as many as 100 different animals, all along just a half-mile stretch of the Purgatoire River.
