Plan a trip to Denver
Nestled in the South Platte River Valley along the eastern edge of the Rocky Mountains, Denver’s location made it an ideal mining settlement during the Pike's Peak Gold Rush in 1858. In the years since Denver's founding, the "mile high city" has grown into a modern metropolis amidst striking natural beauty. Get outside and make use of Denver's 300 days of sun. Wander through the calm Japanese Garden in the well-appointed Denver Botanic Gardens. Explore the beautiful peaks and valleys of the Rocky Mountains with a scenic drive out to Mount Evans, and take an afternoon tour of the Molly Brown House Museum and learn what late 19th and early 20th century Denver life was like.
