Luxury Resorts in Thailand: Beach Resorts, Riverside Hotels and Northern Retreats

The best luxury resorts in Thailand, and its grand hotels, fall into three groups: beach resorts on the islands, grand hotels on the Chao Phraya River in Bangkok, and quiet retreats in the north. Here is how to choose, with some of the hotels we feature.

What “luxury” means in Thailand

Thailand set the standard for the modern Asian resort. Amanpuri, which opened on Phuket in 1988, was Aman’s first hotel, and Bangkok’s Mandarin Oriental has welcomed guests on the riverbank since the 19th century. Today, a top Thai resort usually means a private pool villa, a spa built around Thai massage and herbal treatments, a beach or river setting, and the warm, unhurried service the country is known for. The choice comes down to the setting you want and the season you travel in, not to whether a hotel is “luxury enough”.

Beach resorts: Phuket and Koh Samui

Choose an island resort for sea views, private pools and spa days. Phuket is on the Andaman side (best roughly November to April); Koh Samui is on the Gulf side (driest roughly January to August). See Koh Samui vs Phuket to pick an island.

• Amanpuri Phuket: a secluded beachfront retreat on Phuket’s west coast.
• Rosewood Phuket: a resort on Phuket’s west coast known for its bay setting.
• Amatara Phuket: a Phuket stay for travelers who want a resort-style base.
• Four Seasons Resort Koh Samui: villa-style stays on Samui’s coast.

What sets the island resorts apart

Amanpuri sits on a coconut-palm headland above Pansea Beach and is known for discretion rather than nightlife. Rosewood Phuket is on Emerald Bay, a small cove south of Patong, close enough to the action but completely private. On Koh Samui, Four Seasons spreads its villas over a hillside on the northwest coast, with views across the Gulf to the islands of Ang Thong. For honeymooners, all three are strong choices. Families usually prefer the larger resorts with kids’ clubs and gentle beaches.

Bangkok: riverside hotels

Bangkok’s luxury hotels line the Chao Phraya River, with boat access to temples and markets.

• Mandarin Oriental Bangkok
• Shangri-La Bangkok
• Anantara Bangkok Riverside

Plan your days with things to do in Bangkok.

The Mandarin Oriental is Bangkok’s historic grande dame, with its original Authors’ Wing. The Shangri-La is next to the Saphan Taksin pier and the Skytrain, which makes it convenient for sightseeing. The Anantara Riverside, on the quieter Thonburi bank, has a resort atmosphere and a shuttle boat across the river. Two nights at one of them combines the city’s temples by day with a riverside dinner as the boats light up.

Chiang Mai: northern retreats

• Four Seasons Resort Chiang Mai: a countryside resort north of the city.
• 137 Pillars House: a heritage teak-house hotel in the city.
• Anantara Chiang Mai Resort & Spa: a riverside resort in the city.

The north is best from roughly November to early February; haze is common from February to April.

137 Pillars House is built around a 19th-century teak house that belonged to a trading company, a short ride from the old city. Four Seasons Resort Chiang Mai overlooks working rice terraces in the Mae Rim valley. Anantara Chiang Mai is on the Ping River, and its colonial-era building was once the British consulate. City hotels suit walkers and food lovers; the valley resort suits travelers who want quiet days between excursions.

Beyond the classics

• Krabi: Rayavadee, on the Railay peninsula, is reached only by boat and surrounded by limestone cliffs; Phulay Bay, a Ritz-Carlton Reserve, faces the Andaman islands.
• Phang Nga Bay: Six Senses Yao Noi, on a quiet island between Phuket and Krabi, has hillside pool villas with views of the bay’s karst towers.
• Koh Kood: Soneva Kiri, on a remote island near the Cambodian border, is a barefoot-luxury hideaway for travelers who want total seclusion.
• Hua Hin: Chiva-Som, a destination wellness retreat a few hours from Bangkok, is ideal for a dedicated health program.
• Golden Triangle: Anantara Golden Triangle and Four Seasons Tented Camp sit where Thailand, Laos and Myanmar meet, with elephant programs focused on welfare.

How to choose

• Beach and spa: Phuket or Samui, matched to the season.
• Culture and food: a Bangkok riverside hotel, then a northern retreat.
• Honeymoon or family: two bases: a city stay and a beach resort.

Booking tips

• For Christmas and New Year, many beach resorts set minimum stays and some include a compulsory festive dinner, so check the conditions before you book.
• In the shoulder and rainy seasons, the same villa often costs much less, and the right coast can still be sunny: Samui in July, Phuket in March.
• Ask for airport transfers by the resort or by your travel designer; island resorts can be 45 minutes or more from the airport.
• For a spa-focused stay, book signature treatments before arrival, as they fill up fast at small resorts.
