Geological Wonder And Ancient City All Rolled Into One
This is the Cotton Castle, a World Heritage Site and an amazing place to visit.
It is located in Turkey and it's quite off the beaten path, so one must be determined to trek out to this location.
It is the site of the ancient city of Hierapolis and an unusual geological oddity.
The Cotton Castle is home to 17 hot water springs ranging from lukewarm to boiling hot.
The water drains into the travertine pools resting on top of the cliffs, and visitors are permitted to go for a dip anytime they please.
The entire area is covered in calcium carbonate, which creates an arctic looking environment.
Hierapolis was an Ancient Greek town that was dedicated to being a spa for the wealthy.
Much of the city is now partially buried, but lots of ruins can still be seen by visitors.
