Colorado is the densest craft beer state in America — over 400 breweries for six million people, and the home of the Great American Beer Festival. This trail links the four beer capitals of the Front Range plus a Rocky Mountain detour in one drivable loop: Denver, Fort Collins (New Belgium, Odell), Boulder & Longmont (Avery, Left Hand, Oskar Blues), Frisco (Outer Range) and Colorado Springs. Four to six days, roughly 550 km of driving, 19 breweries worth the detour.
