Sand, shallow water and ruins facing Kastri islet
Agios Stefanos is more than a swim stop. The remains of early Christian basilicas sit immediately behind the shore, and Kastri islet gives the bay a recognisable horizon. The water is often approachable, though conditions still vary.
Do not walk or place belongings on archaeological remains, and never swim to the islet unless conditions, ability and local advice make it genuinely safe. Bring shade outside organised sections and visit early enough to read the site before beach traffic peaks. Pair it with Kefalos rather than racing back to Kos Town for another timed attraction.
