Apostolus Waterfall lies in the mountainous interior of Thassos, north of Kastro, at approximately the coordinates recorded in this listing. It is a small, secluded cascade rather than a managed park attraction. The route through forest and stream terrain is central to the experience, while the water volume changes markedly with rainfall and season.
Independent local route descriptions place the waterfall roughly three kilometers from Kastro by dirt road and path. The final approach can be steep, muddy or difficult to identify, and navigation apps may propose unsuitable shortcuts. There is no verified ticket office, lifeguard, staffed visitor center or guaranteed mobile signal at the falls.
