Three Lakes Trail/Appalachian Trail Loop from Dennytown Road
This loop hike leads to the remains of an old iron mine, passes an attractive lake, and follows the scenic Appalachian Trail along a forested ridge.
From the east end of the Bear Mountain Bridge, proceed north on N.Y. Route 9D for about 8.5 miles to a junction with N.Y. Route 301 in Cold Spring. Turn right and follow Route 301 for about five miles to Dennytown Road, then turn right and follow Dennytown Road south for 1.1 miles to a dirt parking area on the left side of the road.
Proceed to the northeast corner of the parking area (to the right of an old stone building) and follow the blue-blazed Three Lakes Trail, which enters the woods, crosses a stream on rocks, and bears right to parallel it. After passing a swamp on the right, the trail turns left and begins to climb rather steeply. Near the top of the hill, the trail passes an interesting split rock on the right. Just beyond, the trail curves to the left. Leave the trail here and continue straight ahead. You'll soon reach the remains of the Denny Mine.
