I am convinced Chautauqua is Colorado’s best-kept secret and I’m amazed how few locals know about its charms. Located at the base of the Flatirons in Boulder, this National Historic Landmark has rental cottages that are surrounded on three sides with open space that includes 48 miles of hiking trails and thousands of acres of natural lands begging to be explored. On weekends in June, Theatre-Hikes Colorado will take audience members on a moderate hike amidst the scenic backdrop of Boulder Open Space while scenes from “Snow White” are performed along the way. On June 29, don’t miss the Colorado Music Festival’s Young People’s Concert, which is a is a narrated work about a cartoon score being performed at a symphony concert (tickets are $8). The historic Chautauqua Dining Hall (a tradition since 1898) has recently undergone a huge overhaul and the wraparound porch offers some of the best patio dining in Colorado. If you visit on a Saturday, be sure to also visit the Boulder’s Farmer’s Market (the largest in Colorado). Not to be forgotten are Pearl Street Mall’s restaurants, shops, people-watching and Pop Jet Fountain–they never fail to entertain.

^{Situated in Southern Colorado, the Great Sand Dunes National Park is an impressive sight. Shaped by winds blowing from and against the nearby Sangre de Cristo Mountains, the piles of sand climb to more than 750 feet (230 meters), making them the tallest dunes in North America. Sand-boarding, skiing and sledding on the dunes are the park’s most popular activities, and there are medium-size slopes to slide on located near the main parking area. A longer hike to the north brings thrill seekers to a 300-foot (90 meter) slope that tumbles onto into Medano Creek.}
