Boulder, Colorado

Those seeking peaceful solitary travel in the United States can spend their days exploring the mountains and hills that surround Boulder. Eldorado Canyon State Park is about 20 minutes south of downtown, Flagstaff Mountain's approximately two-mile hike is only 15 minutes to the west, and the famed Flatirons (red sandstone structures) are less than 10 minutes distant by automobile. If you're in the mood for some socializing, head to Pearl Area Mall, a lively pedestrian-only street filled with some of the city's top restaurants, stores, and bars.

Outside magazine named Boulder the No. 1 Sports Town in America for a reason. This city's outdoor recreation rivals anything you've ever seen. In a single day, you may hike and bike through the Rocky Mountains, go fly-fishing in Boulder Creek, and downhill ski (or snowboard) at Eldora Mountain Ski Resort. On Boulder's 45,000 acres of untouched nature, you'll never run out of things to do, see, and explore.

Boulder is a postcard come to life, with its stunning terrain and spectacular weather. In this magnificent metropolis, the sun shines more than 300 days every year. It's no surprise that everyone seems upbeat and lively. That is a significant amount of Vitamin D! When you combine it with the fact that the typical winter temperature is a pleasant 35-40 degrees, Boulder is essentially heaven on earth.

Great cuisine is as simple to get by in Boulder as PhDs and athletes. With a plethora of farm-to-table restaurants and locals who are committed to eating locally, it's no surprise that Bon Appetit voted Boulder the "Foodiest Town" in 2010. You can't go wrong here, whether you're drinking a pint at Wild Woods Brewery or eating excellent Japanese sushi at Sushi Tora. Whatever you decide, your taste senses will reward you.
