An eco-elegant resort with exceptional service and luxurious spa treatments in a tranquil natural setting.

Framing a beautiful cove on the north-eastern side of the island, it’s hard to imagine a more romantic and serene private hideaway than The Tongsai Bay. This family-owned hotel was sensitively built without cutting down a single large tree, and that passion for nature and the surrounding environment remains strong today, in harmony with the resort’s commitment to exceptional service. Eco-conscious guests will love the sustainable features throughout, from efforts to reduce the hotel’s carbon footprint by sourcing rice straight from local farmers to a wildlife-friendly approach that is encouraged in all staff.

If you want to relax by the water, take your pick from the expansive freeform pool or the adults-only infinity half-moon pool – both serving up amazing sea views. From the comfort of your lounger, just raise your flag and the waiter will appear to take your drinks order. Or take up a sun bed on the beach and cool off in the calm waters of the bay. In the evening, dine under the stars at the beachside Po-Lad Beach Bistro & Bar or feast on delicious Thai cuisine at Chef Chom’s, one of the island’s finest restaurants.

Each of the beautiful cottages and villas makes the most of the space, with plenty of room to enjoy both indoors and outdoors, and some offering an open-air bath. To be close to the beach and pool, opt for one of the Beachfront Suites. Cottage Suites are higher up the hill and have partial sea views and pretty scenes out across the gardens, while the Seafront Cottage Suites feature spectacular sea views. Presenting the ultimate indulgence, the resort’s range of villas are much more spacious, with a larger balcony or outdoor living area, plus the option of your own private pool.
