On the edge of the Rocky Mountains at 5,430 feet above sea level, Boulder, Colo., is often considered one of the best small cities in America. The laid-back town is populated with organic food junkies, students (and post-grads) who revel in university culture, and hardcore adventurists that enjoy premiere outdoor recreation like hiking, skiing, mountain biking, fishing, rafting and rock climbing. Boulder is surrounded by undeveloped, government-protected open space — naturally preventing urban sprawl — and residents are proud of the city’s relatively small environmental footprint. It’s also become a hot foodie destination — several local chefs have been contestants on Bravo’s Top Chef and the town is known for its dedication to local and sustainable cuisine.
