Our visit to the beautiful Delaware Water Gap country. After all the rains we had this season, it felt like local Amazonia. Here is a bit of info on the falls: Dingmans Falls is the 2nd largest waterfall in PA, with a plunge of 130 feet (pictured 2nd). The boardwalk to it passes by a thin horsetail cascade called Silverthread Falls (1st). Raymondskill Falls is the tallest in the state of PA, only 4 feet shorter than Niagara.
