The famous Tripa of Sfentonis (i.e. the hole of Sfentonis) or Tripa of Zou (i.e. the cavern of life) is 1 kilometer in the east of Zoniana, in the Rethimno prefecture.
It is about 3.000 sq. meters and 270 meters long. The tour is held by a guide on safe aisles in various rooms that are created by huge columns and various colorful stalagmites and stalactites. There are also water tanks in the cavern with amazing colors and the crystal sparkle of the carbon calcium. The life in the cavern is maintained in a certain cycle and with bats, insects and rodents. A spring called “to nero tis Amaltheias” (i.e. the water of Amaltheia) is near the cavern
There are many legends about the cavern. It is said that a Rebel chainis from Sfakia, Sfentonis, had been living in it. One day, as Sfentonis was preparing his food in the entrance of the cavern, a teenager noticed him. The young man asked him for food but Sfentonis killed him in the fear of revealing his hideout. Bones of a young teenager have been found in the cavern, in the entrance of the last room, covered with whitewash that could confirm the legend.
