Kastro ( Skiathos ) was built during the 16th century, by the island’s population who decided to shift to the unconquerable rock, which is located to the northeast of the island. In the past, the narrow drawbridge served as the only link with the island. Remaining in the castle neighborhood are the town walls, the trademark drawbridge, the Turkish baths and remnants of a few churches, all of which make a visit to castle a memorable experience. The castle town was strategically built on a rocky cliff that literally hangs above the sea on the northern coast of the island. One can hike up to the castle town, but it is a steep hike and takes around 3 hours. You can also rent a jeep tour at most travel agencies in Skiathos Town.
