Hi Lesley,
These are Enders Falls, Enders State Park, Route 219, Granby, Ct. There is a series of 6 falls all in a row. They are very unimaginatively called Enders Falls 1, Enders Falls 2, etc. They are all in a 1/4 mile stretch of the East Branch of the Salmon Brook River. When the river is low, you can walk across the rocks to the other side. It is a popular swimming hole for kids in the summer. I can't believe they jump off the cliffs! The pools are only 20-30' across, with a 30' drop! The water is quite chilly, even in the summer.
