Kastro is the remains of the biggest medieval town on
Skiathos which was occupied from the twelfth century till 1830. It was built on a cliff at the north end of the island around 8.5km from the capital
Skiathos Town and that should take just under half an hour in a car or taxi.
Just a narrow strip of land connects the cliff to the island itself. Due to it’s position and fortifications Kastro was a secure place for the areas inhabitants. Now there are the remains of several houses and churches to have a wander around and some fantastic views and scenery to enjoy.
Kastro is not an easy place to get to, you can only drive part way and then you have to walk the rest of the way so probably better suited to an early morning or early evening visit. There is also no shops once you leave the car park so make sure you take some water as you’ll probably need it, there are some fairly difficult paths to walk so we wouldn’t recommend it for kids or the elderly.
Also in the area is a beach known as
Kastro beach so you can make a day of it and spend some time there as well if you want to.
