4 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.

Step out of Denver to go to Rocky Mountain National Park and see Trail Ridge Road, which is approximately 2 hours away. There's much more to do: admire the natural beauty at Denver Botanic Gardens, take your sightseeing to a higher altitude at Mount Evans, cruise along Mount Evans Scenic Byway, and contemplate the long history of Union Station.

Expect a daytime high around 43°F in December, and nighttime lows around 19°F. Cap off your sightseeing on the 2nd (Wed) early enough to travel back home.
