Phuket and Phang Nga Bay on Thailand's Andaman coast

Southeast Asia

Southeast Asia on this list means Thailand's Andaman coast: the quieter west-facing bays of Phuket and the limestone islands of Phang Nga Bay. The sea is warm all year, and the food is a reason to go on its own.

Go from November to April, outside the southwest monsoon.

Where to Go

  • Phuket's west coast: quieter bays and headlands away from the busy towns, with boats to the islands offshore.
  • Phang Nga Bay: hundreds of limestone islands rising from calm water between Phuket and Krabi, with sea caves and hidden lagoons.
  • The Similan Islands: a national park of granite boulders and clear water, known for diving, open in the dry season.

What to Do

Spend a day on a boat in Phang Nga Bay and paddle by kayak into the lagoons inside the rocks. Dive or snorkel the Similan Islands in season. On land, walk Phuket's Old Town with its Sino-Portuguese shophouses and food markets, take a Thai cooking class, and visit the rural villages of Koh Yao Noi by bicycle.

Best Time to Go

November to April is the dry season on the Andaman coast, with calm seas and the best diving. December to February is the most comfortable and the busiest. From about May to October the southwest monsoon brings rain, wind and rough seas, some boat trips stop, and the Similan Islands close to visitors.

Getting Around and How Long to Stay

Phuket has direct flights from the Gulf hubs and Singapore, and short flights from Bangkok. Koh Yao Noi is about 45 minutes by boat from Phuket. We suggest five to seven nights, split between Phuket and Phang Nga Bay if you want variety, with two or three nights in Bangkok before or after.

Where to Stay

Phuket: Amanpuri, Aman's first resort, sits on a headland above Pansea Beach and has its own fleet of boats. Rosewood Phuket is a modern resort on Emerald Bay, a quiet cove just south of Patong.

Phang Nga Bay: Six Senses Yao Noi has hillside pool villas facing the karst islands.

Pairing

Thailand's Andaman coast pairs well with Bangkok and with northern Thailand around Chiang Mai. It also makes a winter beach stop on a longer trip to Asia or on the way to Australia.

Dugong

The dugong is a large, slow marine mammal that grazes on seagrass, and it is listed as Vulnerable on the IUCN Red List. In 2022 Thailand had an estimated 273 dugongs, about 90 percent of them on the Andaman coast, with most around Trang and Koh Libong. Since then seagrass at the key Trang sites has fallen by up to 70 percent, and Thailand's Department of Marine and Coastal Resources recorded an average of 42 dugong deaths a year in 2023 and 2024, more than double the earlier rate. Many died of starvation, and others from boat strikes and fishing gear as they moved into busier waters, including Phang Nga Bay.
