Route: Undermountain Trail (CT)

The Undermountain Trail in Salisbury, CT might be the most popular starting point for hikers in the state of Connecticut. There are two main reasons for this. The community of hikers in this part of the state are hard core, dedicated hikers who enjoy the most challenging trails the state has to offer. People from out of state looking for overnight adventures on the Appalachian Trail also park here as the trail head offers a great 2 mile hike to the Appalachian Trail and numerous mountain tops and waterfalls to explore.  While the Undermountain Trail is often used to access other trails and features, the FKT route is out to the AT (1.8 miles, 1000' elevation gain), and back to the TH.
