COME TO LIFE | Boulder COLORADO DENVER & CITIES OF THE ROCKIES PEARL STREET MALL ONLY IN BOULDER Playfully referred to as the People’s Republic of Boulder , this city was named “Happiest City in the U.S.” by National Geographic and is known for progressive attitudes stemming from its hippie heyday. Today it’s characterized by research centers, the University of Colorado (CU), artsy folks, world-class restaurants and hyper-athletic citizens. SIP A FRAGRANT CUP OF TEA AT THE DUSHANBE TEA HOUSE, WHERE YOU CAN ADMIRE THE INTRICATE PAINTINGS AND CARVINGS ADORNING THE STORIED BUILDING. Afternoon Discover the hiking trails in National Historic Landmark Chautauqua Park , with options to suit every level of hiker and up-close views of the Flatirons — the slanting slabs of red sandstone that are Boulder’s most recognizable landmark. Pro tip: On summer weekends, a free shuttle will take you to Chautauqua or Eldorado Canyon State Park from the CU campus. There’s also the Museum of Boulder , which hosts traveling exhibitions from nationally recognized museums. Or check out Wonder Wonder , an immersive digital-art experience with 18 rooms of light displays, technological contraptions and art encounters. Morning The pedestrian Pearl Street Mall is the city’s hub, lined with historical buildings that now house longtime-favorite shops and restaurants.

Or hook up with JD’s Joyrides to view Boulder’s vibrant Mural Trail from an ebike. At The Ice Coop , the nation’s only indoor ice-climbing gym, try — or even watch — this show-stopping sport. Saturdays and Wednesdays, April– mid-November, stroll Boulder Farmers Market , with a strict sell-what-you-grow policy and a lovely setting next to Boulder Creek.
