A BREATHTAKING ECO-FRIENDLY HOTEL IN TROPICAL SURROUNDINGS

Run barefoot and with a clear conscience at multi-award winning The Tongsai Bay, a pioneering island eco-friendly hotel in the Gulf of Thailand. Lush tropical mountains curl around the private bay, creating a secluded castaway paradise. Explore the pristine beach just for guests — no beach vendors or motorized water sports — or, in select rooms, sink into a signature bath with a view on your spacious terrace before dining on authentic Thai cuisine in the exquisite alfresco restaurants.

  • Five-star luxury hotel created to celebrate and care for its paradise setting
  • Peaceful 28-acre grounds dominated by a crystal-blue bay
  • Unwind in one of the 83 suites, cottages, and villas, many with private plunge pools
  • Relish Michelin-style fine dining or go barefoot at the laid-back beach bistro
  • Find your inner calm in an outdoor milk or floral bath at the Prana Spa
  • Windsurf, kayak, or paddle board on the tranquil, unspoiled waters

The Tongsai Bay delicately balances being an upscale five-star hotel with a wealth of sumptuous amenities and absolute respect for the natural environment. Family-owned, this eco-friendly destination celebrates the sheer beauty of Ko Samui.

Accommodations

View Rooms & Rates

Each of the 83 suites, cottages, and villas is beautifully decorated with dark woods and pops of color to create a homey feel. Plush bedding, large tiled bathrooms, and wood-craft furnishings epitomize luxury and comfort inside, but this is a place for outdoor living. Choose a suite steps from the pool, or a cottage with its own infinity pool and colonial rocking chairs facing the sea. The cottages all have the hotel’s signature outdoor bath with a view for ultimate relaxation.

From the eco-friendly water sports to the peaceful pool served by the Beach Boys team delivering fresh towels, ice water, and drinks from the bar, The Tongsai Bay is true escapism. The tour desk and car rental partner can guide your adventures beyond the hotel, and should you need corporate facilities, the Ga La meeting room is well-equipped, with staff on hand to help you craft a conference to remember.

The Tongsai Bay Dining

Dining

Feel the warm sea breeze at Po-Lad Beachside Bistro & Bar, enjoy an authentic taste of Thailand at the restaurant, or indulge in Michelin-style fine dining. For a truly memorable experience, arrange for chef and staff to serve your meal exactly where you want it.

The Butler’s – Open two evenings a week, this exclusive and intimate dining experience offers a special chance to sample Asian and Mediterranean dishes — think Australian rack of lamb or seared Hokkaido scallops — lovingly prepared by a Michelin-trained chef.

Po-Lad Beach Bistro & Bar – Go casual at this beachside bistro and watch the waves wash over pristine sands as you choose soul-food salads, burgers, pizzas, and Thai dishes.

Chef Chom’s Thai Restaurant – Savor Thailand’s distinctive regional specialties at this courtyard restaurant where the emphasis is on authenticity and fresh ingredients.

Tongsai’s Private Dining Experience – Dine on the beach, your own balcony, or in a gazebo that overlooks the bay — all with your own personal chef and waiter on hand for a completely exclusive experience.

The Tongsai Bay spa

Activities

This is eco-tourism at its finest. Stroll through the organic garden as a chef explains how to create Thailand’s iconic dishes before cooking your own. Soak up the culture in beginner language classes or learn to create carved-fruit table centerpieces. After a game of tennis — or a paddle in the boat-free bay — settle on a beach beanbag to watch a movie under the stars with complimentary butter- or chili-flavored popcorn before indulging at Prana Spa.

Away from the hotel, take a boat trip to Ang Thong National Marine Park, an archipelago of 42 islands off the coast of Ko Samui. The Big Buddha Temple, a 10-minute drive away, is home to a stunning golden statue on a rocky island reached by a causeway.
