Hiking Samaria is a deep, transformative journey through the largest canyon in Europe. You'll descend from the high alpine mountain air of Omalos, trekking 16 kilometers through towering limestone walls that shrink to just a few meters wide at the dramatic "Iron Gates." It is a demanding, 6-to-7-hour physical pilgrimage over loose, rocky terrain, but it rewards you with an overwhelming sense of the Earth's raw power. Your journey ends at the edge of the Sea in the isolated, village of Agia Roumeli. Wash the dust off your boots, dive straight into the deep blue water, and let the island restore you.
