This trailhead provides access to a 1. 7-mile loop trail leading to Fourth Connecticut Lake, the headwaters of the Connecticut River, located on the US/Canada border near Pittsburg, NH.

The parking area is situated at the US Route 3 border crossing station, with the trail beginning near a Nature Conservancy kiosk and featuring steep initial climbing through boundary clearings before descending into boreal forest with boardwalks over muddy sections.

The preserve is open to the public year-round for hiking and wildlife viewing, though pets are not permitted and camping/fires are prohibited.
