Kosta Harbour
37° 17.5′ N · 23° 9.9′ E · approximate
The tiny mainland hamlet facing Spetses across the strait, where the car ferry and water taxis shuttle to the island — with a Blue Flag beach of sand and shallow water.
Practical
Coordinate approx: placed just south of the Kosta ferry landing mapped in OSM — check depths on your chart; no pilot-book anchoring data was found. Kosta is about 4–4.5 km south-east of Porto Heli. Water taxis run 24/7 across to Dapia; Wikivoyage (2014) noted parking about €5/day and the Katerina Star ferry (~15 minutes) — verify locally. Restaurants and cafes behind the beach; KTEL buses connect to Kranidi, Nafplio and Athens. Population about 83. The Spetses Classic Yacht Regatta races in the strait off Kosta in June.
