Arriving in Denver

Almost everyone who visits Denver feels the call of the mountains, and you should really think about renting a car. Even a simple drive along the 15-mile Mount Evans Scenic Byway is a magnificent outing. The “road into the sky” offers astonishing views as you climb in altitude, traveling through three distinct ecosystems and some of the country’s most beautiful landscapes. Once you’re up in the mountains you can abandon yourself to long days of climbing, hiking, or skiing. Even once you get back to downtown Denver, it’s likely you’ll want to spend much of your time outside.

Strolling or cycling through the city is the best way to explore the lovely neighborhoods and parks, and many of the best attractions are nature-themed. The Museum of Nature and Science is packed with fascinating exhibits, and the Denver Botanic Gardens offer 24 acres of blossoming beauty. For a taste of Denver nightlife, head to the lively Larimer Square, where restaurants, clubs, and shops populate the area’s Victorian buildings.
