Vathis is located 11 km northeast of Pothia and has the largest and most fertile valley in Kalymnos. The combination of the bay and the wooded valley full of citrus creates an astonishing landscape. On the slopes of the hills, near the port, there is the settlement of Rina, which was destroyed in the early 15th century by pirates. The church of St. Irini is built there nowadays. At the port there is a boat yard and a safe anchorage for tourist yachts. Next to the port there is a natural aquarium which is definitely worth the visit.
