Fourth Connecticut Lake Trail


Fourth Connecticut Lake Trail is a public trail maintained by The Nature Conservancy that criss-crosses the international border between New Hampshire, United States, and Quebec, Canada, for ending with a loop around the Fourth Connecticut Lake in Pittsburg, New Hampshire. The Fourth Connecticut Lake Trail is one of the few international trails in North America.

Hiking the trail

The parking area for hikers is at the American facility of the Pittsburg–Chartierville Border Crossing, located north of the Pittsburg town center via U.S. Route 3. The trail begins about to the right of the American building, with a small kiosk at the trailhead.
The trail has no cell phone coverage, requires some non-technical climbing, and starts at a good elevation, so one should be prepared even in summer. Pets are not allowed on the trail, and no camping, hunting, or fishing is allowed.
For persons starting in the United States, passports are not needed to hike the trail, as even though parts of the trail are in Canada, the trail starts and ends on the American side of the international border. For persons starting in Canada, a passport or other border crossing document would be required in order to enter the United States at the border facility before hiking the trail.
