Located on the unspoiled island of Koh Yao Noi within two acres (half a hectare) of lush, well-tended gardens, AT20 offers an entire, all-inclusive, private resort designed exclusively for a single group of guests. With spellbinding oceanfront views, the resort can accommodate up to 20 guests across two Ocean Villas, two Family Villas, each with two guestrooms, and four Pool Suites, and offers direct access to a sandy beach overlooking the turquoise waters and limestone islands of Phang Nga Bay.

Designed to maximize the property’s breathtaking views, the resort comprises gracious free-standing structures with distinctive, pointed rooflines inspired by Northern Thailand’s ancient Lanna architecture. The lofty Arrival Pavilion overlooking the resort and its verdant seaside setting is connected via stairs and elevator to the abundance of living and dining areas, the four Pool Suites, and the four Villas set around the vast main swimming pool. Boasting vaulted ceilings, spacious bedrooms, and large bathrooms, all guest accommodations have a serene contemporary aesthetic with Thai teak touches. The two Ocean Villas with their private terraces and double daybeds are positioned closest to the ocean, each with a two-bedroom Family Villa with shared living room positioned behind. The four Pool Suites overlook the resort’s rolling lawns and out to sea, each claiming its own small private pool between the bedroom and the bathroom, and a double daybed on the front terrace.

AT20 offers every facility and service a group of guests could possibly desire during their stay. The glass-walled, air-conditioned Living Sala is complemented by an open-sided Dining Sala – both with incredible views of the bay. There is also a double spa treatment room with jacuzzi, and a fully equipped gym. Open-air settings for dining and relaxation include a sunken lounge deck, a rooftop meditation area, the garden, and the beach, while the games area, children’s pool and waterslide, and in-pool chess and backgammon provide hours of enjoyment. The resort’s discreet and dedicated team of 22 is available around the clock to tailor every detail – from special dining, cultural, and wellness moments, to kids’ activities and exploration of the region – to ensure a bespoke experience that defies expectations.

Breakfast, lunch, and dinner are served each day in different settings across the resort, with every menu tailored according to guest preferences to surprise and delight. Free-flow beverages including juices, premium spirits, cocktails, and wines can be enjoyed whenever a guest desires. Up to 10 spa treatments per day are included, as well as personal training, non-motorized water sports, guided cycling tours, movies by moonlight, Thai cooking classes, cultural entertainment, and more. A complimentary round-trip airport transfer makes traveling to AT20 a breeze, and up to eight hours of complimentary babysitting and a daily children’s activity program keeps kids entertained.

Beyond the comprehensive inclusions, the expert local team can arrange any possible experience offered in Phang Nga Bay, ensuring that transportation is booked, and costs are clear. Rock climbing, scuba diving, and island-hopping cruises by longtail boat or private yacht can be easily organized, as can Muay Thai Boxing training, private yoga sessions, and visits to the Phuket Ethical Elephant Sanctuary. The region is renowned for its pristine natural beauty, and the island is part of Ao Phang Nga National Park, making it a sanctuary for wildlife including hornbills, sea otters, and green turtles.
