John Boyd Thacher State Park is a state park located 15 miles (24 km) southwest of Albany, New York near Voorheesville, in Albany County on State Route 157. Located mostly atop the Helderberg Escarpment, the park has several hiking trails that offer panoramic views of the Green Mountains  in Vermont  and the Hudson Valley.

From the Indian Ladder parking lot, the visitor descends 60 ft (18 m) to the base of the escarpment via a metal staircase. From here the trail follows the base of the escarpment passing under the Minelot Falls and by the stream exiting from a small cave in the base of the rocks. This water is actually from Thompson Lake,[4]  some two miles (3 km) away, which makes its way through the porous limestone until it exits here. At the end of the trail, a second set of metal staircases take the visitor back to the top of the escarpment. The trail then continues back to the parking lot, offering excellent panoramas.
