Insider information on Harriman trail safety tips

Trail guidelines are essential! Please observe one-way designations and for those on snowshoes or fat-tire bikes, avoid groomed ski tracks. Fat-tire bikers must use tires with a minimum width of 3.7 inches and maintain a tire pressure of 5 P.S.I. or lower. Additionally, riders should exercise caution by riding on the firmest section of the trail and avoiding soft snow conditions, aiming not to leave ruts deeper than 1 inch.
