Step back in time with an exclusive boat tour to Ancient Karthea, Kea’s hidden archaeological wonder. Only accessible by boat or a scenic hike, this once-powerful city-state offers a rare glimpse into Greece’s classical past, surrounded by the untouched beauty of the Aegean.

Set sail to Kolona Beach, one of the most breathtaking spots in the Aegean. This stunning double-sided beach, where golden sand divides two shimmering turquoise bays, is the perfect island escape. Swim, sunbathe, and experience the raw beauty of the Cyclades.
