Mesonas gorge is located on the northern slopes of the mountains of Thripti, near villages Kavoussi and Avgos. It is a short gorge 4km long. The canyon connects the Plateau of Thripti to the plain of Kavoussi. The canyon is ideal if you like canyoning, crossing a narrow gorge, climbing with ropes and swimming in the waters of the gorge. Mesonas Gorge starts quite smoothly with less roping and more walking. The entire canyon is crossed smoothly except its last part, where its form changes and it turns to a very narrow passage with high walls. The canyon does not have a lot of water and the flow stops in the middle or late spring.
