Denver Museum of Nature & Science
2001 Colorado Blvd., City Park
One of the better nature and science museums we've visited, the scientists at DMNS lead globally significant work, including the excavation of an important archaeological site at nearby Snowmass Village, called the Snowmastadon Project, where they excavated thousands of fossils, including the bones of a Columbian mammoth. In addition to the requisite planetarium, gems and minerals collection, fossils, mummies, and taxidermy, they also have one of the region's only IMAX theatres. In 2014, the museum completed the brand-new Discovery Zone, a totally interactive space for kids ages 3-5, where littles can excavate fossils, play with water features, and create art projects.
