Threading through the countryside between Houlton and Phair Junction, this thirty-seven-mile route is among the longest multi-use trails in the state. Largely gravel, and in some places wide enough to accommodate logging trucks (use caution), it connects the small communities of Monticello, Bridgewater, and Mars Hill to bigger towns like Presque Isle and Houlton. Paralleling Route 1, this is an old train corridor that once took the timber and potatoes of The County to mills and markets in the south, and it wends its way through farmlands, woods, and wetlands, making for good wildlife viewing. Fairly level, it's great for walking, biking, and cross-country skiing. Just be sure to watch out for motorized vehicles. And pack plenty of water and supplies with you because this is remote country. For more information and directions visit http://www.maine.gov/cgi-bin/online/doc/parksearch/index.pl.
