After stopping at the Ethia Visitors’ Information Centre where you will learn about the Protected Area of Asterousia, continue towards the Vorno (or Ethia, or Chavga) Gorge, the largest gorge on the northern side of Asterousia. The typical limestone rocks, some of which are crumbling, are clearly visible above, so you need to be very careful of landslides. From the entrance to the gorge the rising of Asfentilia is visible, where scientists from the Natural History Museum of Crete have located rare fossils, which will be studied to contribute significant new data on the paleontological history of the island. Water only crosses this gorge after heavy storms. It is generally open and features a long hiking path at its exit, meeting the Anapodaris River, which waters the large valley of Mesara. The gorge can be also crossed on foot.
