The Goniano gorge is the unique passage which connects Sklavokampos and Gonies with Tylisos. Its length is 3 km. and is relatively wide and straight. Reaching though the exit (in the point where a monument of those killed during the 2nd World War is in the road to Gonies) the gorge turns abruptly towards south and before it comes out of the limestone mass follows an irregular and abrupt course.
Usually the visitors come out of the canyon before entering the wild section till the exit of the gorge near the village Moni. However this section, also known as Moniano Gorge after Moni is the most beautiful part of the gorge with very narrow passages and vertical cliffs. Moniano Gorge is not accessible due to 5m waterfalls.
