 While some say that the gorge is 18 km long, this distance refers to the distance between the settlement of Omalos on the northern side of the plateau and the village of Agia Roumeli.In fact, the gorge is 16 km long, starting at an altitude of 1,250 m at the northern entrance, and ending at the shores of the Libyan Sea in Agia Roumeli.The walk through Samaria National Park is 13 km long, but one has to walk another two kilometers to Agia Roumeli from the park exit, making the hike 15 km long.
