One&Only Kéa Island: 160-acre Cycladic clifftop palace with Atria, private cliffside infinity pool villas, and Guerlain Spa

Perched with monumental modern Cycladic architectural majesty across 160 protected clifftop acres on a secluded western bay of the authentic island of Kéa in the Cyclades, Greece (the closest Cycladic island to Athens, reached via a 30-minute private speedboat or helicopter transfer from Athens International Airport/Lavrio Port), One&Only Kéa Island opened in 2024 as Greece’s premier ultra-luxury clifftop sanctuary grand palace. Masterfully designed by celebrated architect John Heah, the 63-villa luxury haven blends local hand-cut stone, Greek olive trees, and floor-to-ceiling glass framing panoramic Aegean sunsets. Featuring the acclaimed Greek dining institution Atria, the vibrant Kosmos lounge, private freshwater infinity swimming pools in every single cliffside villa, and the monumental three-story Guerlain Spa, this property is the Cyclades’ ultimate luxury grand palace.

Arrival introduces travelers to unvarnished Cycladic island splendour and Aegean sea majesty: personal Lifestyle Butlers greet guests at the private resort marina dock on Vroskopos Bay before transferring in electric open-air buggies up the stone clifftop road to your private pool villa with private infinity pool, dramatic sunset terrace, and chilled Greek Assyrtiko wine with warm olive tapenade and artisanal honey cheese pastries. Day-one logistics focus on coordinating bespoke Kéa sailing, diving, and historical pursuits: boarding private motor yachts to dive the famous HMHS Britannic shipwreck (sister ship of Titanic resting off Kéa) and explore ancient underwater sea caves (steps away), private guided hiking along ancient stone trails to the archaic ruins of Karthea (15 minutes away), swimming in your private cliffside infinity pool or the main resort pool, indulging in Greek royal honey and olive therapies at Guerlain Spa, sipping signature cocktails at Kaiki on the beach, and reserving dinner at Atria.

Palace living balances active Aegean yachting with serene clifftop wellness: The Guerlain Spa spans three levels featuring private luxury treatment suites, outdoor ocean-view hydrotherapy plunge pools, sauna gardens, and therapies utilizing Guerlain’s Orchidée Impériale and Abeille Royale skincare. Dining is an extraordinary Greek-Aegean culinary summit: refined gastronomy at Atria (featuring locally caught sea bream, lobster kritharoto, and Greek Grand Crus), beachfront dining at Kaiki on the bay, mixology at Kosmos, and in-villa royal dining.

Accommodations comprise 63 standalone cliffside villas and multi-bedroom private compounds styled by John Heah in local stone, white marble, private freshwater infinity swimming pools, and expansive verandas framing the azure Aegean Sea ranging from 110 to 480 square metres. Each residence features dedicated 24-hour personal butler service, plush king beds with custom linens, and marble bathrooms with deep soaking bathtubs, embedded TV mirrors, and custom amenities.
