Remember to take a hammer! This is cool...
Ringing Rocks Park is a 128 acre park nestled in the woods in Upper Black Eddy. Located within the park is a field of boulders, about 7-8 acres in size, that have an unusual property. When the rocks are struck with a hammer or another rock, they sound as if they are metal and hollow and ring with a sound similar to a metal pipe being struck.
The park also has Bucks County's largest waterfall.
