Fodor's Expert Review Museum of the Rockies
Here you'll find a celebration of the history of the Rockies region, with exhibits ranging from prehistory to pioneers, plus a planetarium with laser shows. Most renowned is the museum's Siebel Dinosaur Complex housing one of the world's largest dinosaur fossil collections along with the largest-known T-rex skull, a Mesozoic Media Center, and a Hall of Giants complete with sound effects. Children love the hands-on science activities in the Explore Yellowstone Martin Children's Discovery Center and (in the summer) the living history farm. Tinsley Homestead, with home-crafts demonstrations, including butter churning, weaving, and blacksmithing is open Wednesday through Sunday.
