One&Only Kéa Island is a glamorous Greek island retreat positioned on one of the most sought-after beaches in the Cyclades—only 45 minutes by speedboat from Athens. Sleek private pool villas with commanding Aegean views set the tone at this clifftop resort, home to a 100-metre beach and buzzing Bond Beach Club. Additional facilities at the luxurious One&Only Spa, inspired by Greek sophrosyne, are spread over three floors and include signature treatments, holistic practices, and a dramatic indoor/outdoor pool. There are adventures on land and at sea to embark on as well, from diving historic wrecks to hiking ancient trails. Chic and unspoilt, Kéa Island is a rare uncut gem, where real Mediterranean living meets a sophisticated island dream.
