These two beautiful sandy-pebbly beaches lie beside the ancient ruins of Karthaia and are reached on foot via hiking trails. The effort is rewarded with clear water, dramatic scenery and a memorable swim among one of Kea’s most important archaeological landscapes.

Kaliskia is a small, unspoiled beach with emerald water and welcome natural shade from trees. It is a rewarding stop for independent explorers, particularly when combined with the walk to ancient Karthaia.
Agios Filippos is a quiet, remote beach of sand and fine pebbles, accessible by boat or on foot. Its isolation and crystal-clear water make it a good choice for those seeking a more adventurous day by the sea.
Koundouros is one of Kea’s best-equipped beaches, with sunbeds, beach bars and a choice of water sports nearby. It is a popular, sheltered bay for families and visitors looking for comfort and services.
Pisses is a long, sandy beach on the west coast, framed by hills and backed by tamarisk trees. With clear water, a peaceful setting and a nearby taverna, it suits visitors seeking a quieter, more traditional beach day.
The remarkably well-preserved Tower of Agia Marina is a 4th-century-BC Hellenistic watchtower in Kea’s interior, between the ancient cities of Korissia and Poiessa. Rising beside the small church of Agia Marina, it stands at a crossroads of ancient routes and is considered one of Greece’s finest surviving ancient square towers.
Located in Ioulida, the museum displays artefacts spanning thousands of years of the island's history. Highlights include prehistoric pottery from Ayia Irini, ancient sculptures, inscriptions and everyday objects that illustrate Kea's important role in the Cyclades from prehistoric through Roman times.
