The great waterfalls are in the gorge at a distance of 4km from the village Agios Ioannis of Parnonas. The big waterfall has height 70m and the small one 45m. The climbing clubs organize canyoning and rappel there. These unique waterfalls are some of the most beautiful, but unknown miracles of nature of Parnonas. The rocks around the waterfalls are brown and the waterfalls harshly on them. There are smells of oregano, sage as the small plane-trees make a picturesque scenery. In summer there is a pond for swimming.
