There are several caves on Andros. Most are not explored or mapped by speleologists yet. The Foros cave in Aladino, at the foot of the Gerakones Mountain, is open to the public since 2010. The cave is small, only 57 m deep, but rich with impressive stalagmites, stalactites and helictites in many different shades. The temperature inside the cave is all year around 16 degrees and the humidity is 75%.
