Gythion. What could be more off the beaten track than a genuine ghost town? Gythion itself is a traditional Greek fishing port, packed with shops, tavernas, and authentic old buildings. But its main draw for visitors lies an hour – and several hundred years – away, in the abandoned city of Mystras. Known as the ‘Byzantine Pompeii’ and best discovered on the Mystical Mystras shore excursion The small seaside town of Gythion is overlooked by the awe-inspiring Mount Koumaros. Wide green vistas surround the citadel, and the best views across the site have an unforgettable fairy-tale flavor.
