5 Best Sights in Denver, Colorado

Outdoor cafés and tempting shops line this pedestrian-only 18-block, 1¼-mile thoroughfare, shaded by red-oak and locust trees. The mall's businesses run the entire socioeconomic range. There are popular meeting spots for business types at places like the Yard House in the Sheraton Hotel; a front-row view of the many street performers and goings-on from restaurants' sidewalk patios; and plenty of fast-food chains. Although some Denverites swear by the higher-end Cherry Creek Shopping District, the 16th Street Mall covers every retail area and is a more affordable, diverse experience. You can find Denver's best people-watching here. Catch one of the free shuttle buses at any corner that run the length of downtown. Pay attention when you're wandering across the street, as the walking area and bus lanes are the same color and are hard to distinguish.

The grande dame of Denver hotels was built in 1892, and is still considered the city's most prestigious address. Famous guests have included President Dwight D. Eisenhower, Winston Churchill, and Beyoncé. Even if you aren't staying here, the Brown Palace lobby is a great place to sit on comfortable old couches, drink tea, and listen to piano standards (or harp, during afternoon tea). Reputedly this was the first atrium hotel in the United States; its ornate lobby and nine stories are crowned by a Tiffany stained-glass window.

This is one of the finest museums of its kind in North America, with constantly changing hands-on exhibits that engage children up to about age 10 in discovery. A three-and-a-half-story climbing structure soars through the center of the museum, complete with a bridge and gondola, along with a water area featuring geysers, pumps, and a 30-gallon structure that replicates a toilet flushing. Also among the 16 indoor playscapes and an outdoor area are a teaching kitchen where kids can cook real food; an art studio staffed by artists in residence; a grocery store; a veterinary office; and Fire Station No. 1, a real fire hall with a pole and kitchen. One of the biggest attractions is the Center for the Young Child, a 3,700-square-foot playscape aimed at newborns and toddlers and their caregivers; or little ones can enter Bubbles Playscape, where science and soap collide in kid-made bubbles up to 6 feet long.

More than 300 artists contributed to this Denver variation on Santa Fe's psychedelic, immersive art experience in an even bigger space, here called Convergence Station. Four floors are packed with funky art installations, tunnels, platforms, and interactive pieces, with music and other sound accompaniments. The overall effect is a bit of a fever dream, with clever and humorous takes on everyday objects interspersed with video and storytelling through dioramas. Entry is by timed ticket only, but once you enter, you can stay as long as you'd like. All ages will want to spend a few hours here, but kids especially become transfixed by the sensory overload. It's open Sunday through Thursday from 10 am to 10 pm and until midnight on Friday and Saturday. Adults-only nights and live music events are peppered throughout each month.

The exquisite 9,000-seat Red Rocks Amphitheatre, amid majestic geological formations in nearby Morrison, is renowned for its natural acoustics, which have awed the likes of Leopold Stokowski and the Beatles. Although Red Rocks is one of the best places in the country to hear live music, be sure to leave extra time when visiting—parking is sparse, crowds are thick, paths are long and extremely uphill, and seating is usually general admission.
