The Thirteen Bridges hike is a beautiful 2-mile horseshoe-shaped trail that brings hikers over thirteen old carriage road bridges that pass above Gory Brook. I approached it from the Pocantico River trail, where, after a short walk the trail descends from the ridge that parallels the lower part of the trail.
The bridges are nothing special, so much so in fact that I realized that I had never actually taken a picture of them (you can find a picture of one of them here). They are nowhere near as impressive as the stone bridges on the preserve.
