The trip
In 1966 a bulldozer operator in Rocky Hill turned over a slab of sandstone and found dinosaur footprints. Then more. Some two thousand tracks, made about 200 million years ago by a big Jurassic predator (the tracks are named Eubrontes; the leading suspect is a Dilophosaurus relative). The state built a geodesic dome over the best five hundred and made it a park.
The dome is the show: a raised walkway over the actual trackway, lighting that rakes the prints into relief, and life-size models for the imagination assist. It's compact, hits hard, and lands perfectly in the hour a young kid gives a museum.
The Dinosaur Place has the statues. This place has the actual footprints. Watching a kid work out that a real dinosaur stood in THIS spot, in THIS rock, is watching a brain get bigger in real time.
The casting area is the sleeper move that separates prepared dads from the rest. Bring a quarter-cup of cooking oil, ten pounds of plaster of Paris, a bucket, and rags, and your kid pours a real cast of a real dinosaur track and takes it home. It's free with the supplies, seasonal, and it becomes THE object on the shelf.
Outside is free entirely: flat trails, a butterfly garden, and an arboretum that's a legitimately pleasant walk while the plaster sets.
Do this and The Dinosaur Place as the two halves of the dino curriculum: statues and splash pad there for the spectacle, real tracks here for the moment it becomes true.

Dad tips
- βΈTHE CASTING SUPPLIES. Plaster of Paris, cooking oil, a bucket, rags. Buy them the night before; there is no gift-shop rescue for this one.
- βΈCasting is roughly May through October and the area can queue on summer weekends. Morning arrival wins.
- βΈThe dome is an hour, done well. Pair with the free outdoor trails or plan a second stop; Rocky Hill is 20 min from Hartford's museums.
- βΈRainy day? The dome plus casting under the overhang still works. This is the best wet-weather dinosaur move in the state.
- βΈRead up on Eubrontes for the car ride. When they ask what made the tracks, 'a mystery predator we only know by its footprints' beats any name.
What the kids enjoyed
- βStanding over real tracks and doing the math
- βPouring their own plaster cast
- βThe raking light making footprints appear across the slab
- βThe butterfly garden while the cast set
What to bring
- βPlaster of Paris (10 lb), quarter-cup cooking oil, bucket, rags, paper towels
- βA box or towel to carry the wet cast home flat
- βSnacks for the arboretum wait
- βPatience: the cast takes a while to set and it's worth every minute
Best time to visit
Any; it's the best rainy-day dino option in the state. Casting is seasonal (roughly May-October), check before promising.
