1 Best Sight in Hartford and the Connecticut River Valley, Connecticut

Dinosaur State Park

In this park in Rocky Hill, about 9 miles north of downtown Middletown (halfway to Hartford), see 500 tracks left by the dinosaurs that roamed the area some 200 million years ago. The tracks are preserved under a giant geodesic dome—1,500 more are buried for preservation—making this one of the largest dinosaur-track sites in North America. You can even make plaster casts of tracks on a special area of the property.   To make a plaster cast, BYO 1/4 c. cooking oil, 10 lb. of Plaster-of-Paris, cloth rags/paper towels, and a 5 gal. bucket!
