Forty Mountain Trail.

Forty Mountain Trail is a 3-mile route in the Adirondacks, moderate in length for a half-day outing. The trail name suggests a summit destination, typical of the region's mid-elevation peaks that offer forest walking with potential for limited views. Check locally for current trailhead access and whether the route connects to any larger trail networks in the area.
