Boat access and limited on-island infrastructure make a local charter or dive center the practical way to visit.
Praso Island sits in the Petalioi cluster off southern Evia and works as a boat-based Aegean outing rather than a shore convenience stop. The site mixes rocky terraces, seagrass edges, and sandy pockets, so it suits relaxed exploration on settled days. Expect a quiet, lightly developed setting with clear water and a straightforward island profile for divers who like open-water scenery.
