The Tongsai Bay Resort in Koh Samui, Thailand


The Tongsai Bay opened its doors in July 1987 and became the first five-star luxury hotel on Koh Samui, under the umbrella of The Imperial Hotel Group on the tropical island of Koh Samui, Thailand. The 28 and a half acres of lush green natural landscape wrap around the hillside overlooking the bay that welcomes over 66 different species of birds.

Just 10 minutes away from the airport, Chaweng and Bo Phut, the Tongsai Bay Resort sits in a bay just to the north of Choeng Mon beach. As the only occupant of this attractive stretch of sand, the resort offers both isolation and easy access to the rest of the island.

Address: 84 Moo 5, Bo Phut, Ko Samui Surat Thani, 84320, Thailand.

Style & character

The exquisite villas of the Tongsai Bay Resort tumble down a green horseshoe-shaped hillside to a private beach and offer a real sense of seclusion. Great care has been taken to integrate the buildings, some with broad terraces and private pools, into their natural surroundings.

Both villas and beachfront suites are furnished in contemporary Thai style – darkwood tables and beds, hardwood floors and vivid paintings dominate the interiors.

The resort prides itself on its environmental awareness: no chemicals are used in the garden and there’s a water treatment plant for the bio chemicals used in the hotel’s laundry.

Service & facilities

Service is excellent, friendly but never intrusive.

The free-form pool by the beach is a great hang-out for families while the half moon shaped pool up the hill is reserved for adults. The Tongsai Bay Resort provides complimentary paddle boards, kayaks, a catamaran. Windsurfing is also possible. The water gets deep quickly which is great for swimmers, but not so good for children who are better off sticking to the pool.

There is a gym, a spa with three steamrooms, a yoga room and a tennis court. The resort organises various activities and events including a once-weekly film show on the beach and music performances.

Grown ups can relax in the Ga-La room which offers a pool table, a small library, a large TV and space for small conferences or meetings.

All rooms have unusually large and spotless bathrooms. Rooms on the first and second floor also have a tub on the balcony. The ground-level rooms are ideal for families as children have close access to the pool. All the usual amenities are on offer: air-conditioning, safe, TV, DVD player and a minibar.

Food & drink

Chef Chom’s offers authentic traditional Thai food. Down by the pool, Pol-Ad Bistro and Bar serves international cuisine, with some vegetarian options. The attached bar is the perfect location for a pre-dinner drink.

The Butlers, a wine and tapas bar, is open three nights a week.

Breakfast is both buffet and à la carte. The freshly made juices are excellent and there are eclectic offerings such as sushi, but the basics – breads, cheeses, cold meats, fresh fruit, cereals, yoghurt etc. – are also well covered.

The resort has its own organic garden which supplies herbs, fruits and spices to its restaurants. The weekly beach barbecue, with a focus on sea food, is one of the best on the island.

Access for guests with disabilities?

The hotel surroundings and steps can be a challenge but wheelchair ramps can be provided.


The Sip Room offers a PlayStation, beanbags and board games. Kids can watch movies while their parents have dinner next door. A babysitter service is available on request.
