There are several caves in Andros. Most are not explored or mapped by speleologists yet. The Foros Cave in Aladino, at the foot of 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 16 ˚C all year around, and the humidity is 75%.
