Vagionia is a beautiful, tranquil bay with transparent waters in the northern part of Poros. Visitors may enjoy a refreshing swim and the amenities offered, including umbrellas and sunbeds, along with a light snack accompanied by ouzo or wine at the snack bar. Vagionia is famous because of the sunken city at the sea bottom, where divers can see the cobblestone roads and foundations of ancient houses. This area is also ideal for snorkeling and relaxing family holidays.
