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.

Explore hidden gems such as Eldorado Canyon State Park and Mount Falcon Castle Trail. Take a break from the city and head to Bear Creek Lake Park and Windrider of the Rockies. Venture out of the city with trips to Boulder (Mesa Trail, Guided Electric Cruiser Bike Tours, &more) and Frisco (Frisco Bay Marina, Frisco Historic Park and Museum, &more). Next up on the itinerary: look for all kinds of wild species at Rocky Mountain Arsenal National Wildlife Refuge, admire the majestic nature at Cherry Creek State Park, contemplate the long history of Dinosaur Ridge, and engage your brain at Butterfly Pavilion and Insect Center.
