If you choose to wade take your shoes off or take an extra pair to change into later; I rock-hopped at a spot I located just upstream from the “official” crossing, and was able to get across with little difficulty.

What Gives the Big Falls Swimming Hole Its Turquoise Appearance?

As I mentioned earlier, one of the big draws to the Big Falls swimming hole is the turquoise-colored water.

The water here has that apparent color because as the Stony Fork erodes the underlying limestone, calcium carbonate crystals are released, and they act like tiny prisms that selectively scatter the blue-green wavelength color you see.

The beautiful turquoise waters at the Big Falls swimming hole in Tioga County Pennsylvania is one of the reasons why this swimming hole is so famous.

The erosive properties of the Stony Fork have also, over time, given the stream bed its beautiful contoured appearance.

If you’ve ever visited Rock Run in the McIntyre Wild Area, you’ll have seen similar erosive forces and turquoise-colored waters around some of the swimming holes there as well.
