Greece has one of the most unique places of all. The Voidomatis Springs, a tributary of the Aoös, gives a completely curious swimming experience that will live long in the memory.Voidomatis is a tributary of the Aoös, one of the major rivers in Greece, and it runs in the north-western mainland Ioannina department. Just 15km long, it nevertheless cuts through some of the absolute greenest scenery you will find anywhere in Greece or its islands, and this is the primary reason for traversing it. Whether on boat or by swimming, it’s a great place to experience, and is particularly well known for its incredibly clear waters. The name of the river itself derives from the Greek word for ‘the eye of the Ox’, referring to the blue eyes of oxen being a reflection of the water. A popular place for extreme sports like rafting, it does have some degree of risk to it. When visiting, you must always be aware of the risks of drowning, especially if you are going to visit the springs, which give the region its reputation as a unique and extremely engaging swimming location.
