A great hike to take is a walk up the gorge in Watkins Glen, N.Y. It is amazing place with numerous waterfalls to explore. It is a state park and a main attraction in the area and can be busy in the summer months. When I lived in the area I would visit in the spring and fall time so I could have quiet times to hike and photograph, plus I never had to pay the entrance fee when using the upper access point at that time of year. The water in this gorge is spring fed and is very cold even in the summer. There are many other gorges with waterfalls in this region that are rarely explored that I preferred to spend most of my time, but Watkins Glen is a majestic place with beautiful waterfalls.
