11 days in Denver Itinerary

Aptly nicknamed the "Mile-High City," Denver sits at an altitude of 1,600 m (5,280 ft) above sea level, located right where the Great Plains give way to the Rocky Mountains.

Explore Denver's surroundings by going to Rocky Mountain National Park (Many Parks Curve Overlook & Trail Ridge Road), Estes Park (Art Center of Estes Park Gallery, Estes Park Guided Tours, &more) and Hotel de Paris Museum (in Georgetown). There's much more to do: take your sightseeing to a higher altitude at Mount Evans, get to know the resident critters at Denver Zoo, take in nature's colorful creations at Denver Botanic Gardens, and see the sky in a new way at Denver Museum of Nature & Science.
