Poesten Kill Gorge Park protects a dramatic little ravine on the edge of Troy, where the Poesten Kill cuts through rock before reaching the Hudson. It is a compact place, but the gorge gives the city a surprisingly wild pocket.
The park is best for a short walk and waterfall views, especially if you want something outdoors between Troy's architecture, campus sights, and riverfront. Stay on marked paths and respect closures, since gorge edges and wet rock can be unforgiving.
