An outdoor dinosaur park spread across a hillside north of downtown, the George S. Eccles Dinosaur Park has over 100 life-sized dinosaur sculptures set among native plantings and walking paths. It is primarily aimed at families but there is nothing condescending about it — the models are scientifically up-to-date and the setting, with views over the city and mountains, makes the whole thing feel less like a theme park and more like an open-air museum.
The park includes a real fossil preparation lab where visitors can watch paleontologists working on actual specimens, which is genuinely interesting for adults. The adjacent Natural History Museum of Utah has strong connections with the facility and the interpretive material reflects serious science. Worth an hour or two, especially with children.
