Vagionia Beach is a secluded pebble-covered bay located on the northern coast of Poros island, facing the Saronic Gulf. The beach is notable for its deep, clear blue waters and the presence of submerged ancient ruins visible from the shoreline. The seabed contains remains of an ancient settlement, including stones and pottery fragments, which can be explored by snorkeling. The terrain is primarily comprised of smooth white pebbles rather than sand. It remains one of the quieter swimming spots on the island, removed from the heavily developed harbor areas of Galatas and Poros Town. A small, seasonal beach bar typically operates during peak summer months to provide refreshments.

Do not attempt to walk here from the main port without adequate footwear and sun protection, as the path is unshaded and rocky.
Respect the archaeological nature of the site by not removing or disturbing stones found in the water.
