The hills are alive with the sound of... your huffing and puffing. The 2,500-acre property, owned by the von Trapp family (yes, that von Trapp family), offers more than 37 miles of trail to suit any trail runner's need. While you must buy a day pass to use the trails, the $10 is well worth it. Tackle the short but steep Stowe Pinnacle Trail for a decent challenge, or take Sugar Road out and back for a moderately difficult run up to four miles.
