Samaria gorge is a national park in Crete which is a major tourist attraction, especially for hikers. It is situated in the regional unit of Chania. The walk through National Park is 16 km long. The most famous part of the gorge is the stretch known as Iron Gates, where the width is only 4m and the height of almost 300 m.
The visitors walk down the gorge from Omalus plateau to Agia Roumeli on the Libyan Sea, at which point tourists take ferries to the nearby village of Sougia or Hora Sfakion, where they could spend a night there. Alternatively, they take a coach back to Chania. The walk takes five to seven hours and can be strenuous, especially at the peak of summer.
