This a great easy vertical adventure near metro northwest Boston along groomed trails through the woods, with lots of interesting historical features such at the Ice Age carved Trophe Chasm (bordered with large granite boulders), and more modern items such as the ATT Transatlantic Cable, and a World War II era Air Force radar testing station. Well worth it in any weather, never crowded, trailhead parking. Highly recommend.
