Feraklos castle actually used by pirates before the Knights of St. John ousted them, reinforced the castle than used it as a prison. Reached from the track by a footpath leading to steps. It is a good climb and fairly rough underfoot. Make a mental note of the entry point into the castle since this is much less obvious on the return. Like many of these fortifications on the islands, the walls are the only significant remains. This one is no exception and the inside is overgrown with shrubs and other vegetation. Narrow footpaths lead around the enclosure and there are excellent views from the walls down to Agathi beach and to Haraki in the other direction.
