Great place to hike or ride with your dog off leash. The area is maintained by Fellowship of the Wheel (http://www.fotwheel.org) and the Town of Colchester. Trails are well marked, maintained and split between Easy, Intermediate and Hard. Trails range in length with a reported max of 8 miles of trail. When hiking, be on the watch for riders, when riding be on the watch for hikers. All in all, a great place for a quick hike or ride.
Off northbound exit on I-89 take a right on Rt. 7. At second light take a right. When road takes a sharp right, there is a Sunny Hollow Natural Area Trails. Follow gravel doubletrack and head all the way to the kiosk, you'll see a map and a couple of single tracks leading you in
