Harvard Museum of Natural History

This historic museum boasts a vast and slightly creepy collection of stuffed, bottled and dried creatures from around the globe, from llamas and coelacanths to butterflies. Fossil-mad children can gawp at dinosaur skeletons and admire the 42-foot kronosaurus, a prehistoric marine reptile, while rock fans will head straight for the meteorites and gemstones. Your entry charge includes admission to the interconnected Peabody Museum of Archaeology & Ethnology.
