Watkins Glen State Park is the most famous of the Finger Lakes State Parks located on the edge of the village of Watkins Glen, New York, south of Seneca Lake in Schuyler County. The main feature of the park is the hiking trail that climbs up through the gorge, passing over and under waterfalls. The park has a lower part that is next to the village and an upper part that is open woodland.
Watkins Glen State Park is in a 400-foot-deep narrow gorge cut through rock by a stream that was left hanging when glaciers of the Ice age deepened the Seneca valley, increasing the tributary stream gradient to create rapids and waterfalls wherever there were layers of hard rock. The rocks of the area are sedimentary of Devonian age that are part of a dissected plateau that was uplifted with little faulting or distortion. They consist mostly of soft shales, with some layers of harder sandstone and limestone
The gorge path winds over and under waterfalls and through the spray of Cavern Cascade. Rim trails overlook the gorge. Campers and day-visitors can enjoy the Olympic-size pool, scheduled summer tours through the gorge, tent and trailer campsites, picnic facilities and excellent fishing in nearby Seneca Lake or Catherine Creek, which is renowned for its annual spring run of rainbow trout.
