What is southern Thailand known for?
In February, Phuket's driest month, the Andaman is calm and clear. You wake in a pool villa above the sea and swim before breakfast. By the afternoon you are at anchor off Phi Phi. Southern Thailand is known for its beaches and islands, from Phuket and Phi Phi on the Andaman Sea to Koh Samui in the Gulf. Limestone cliffs, clear water and top resorts make it the country's main holiday region.
Southern food is hot, rich with turmeric, fresh herbs and seafood. Old Phuket Town and Songkhla show a long history of trade with China and Malaysia.
The one decision that matters is which coast, in which month. Our call for a first trip is Phuket, for its villas, restaurants and yacht marinas. For quiet as a couple, choose Koh Samui, Khao Lak or the small islands of Trang. A group can split the stay between a Phuket villa and a few days at sea.
Andaman coast or Gulf coast: which is better in your month?
Choose the Andaman coast from December to March and the Gulf coast from February to April. The two coasts take their heavy rain in different months.
From May to October, the southwest monsoon brings rain and rough seas to the Andaman side. From May to August, Samui and the Gulf islands are the better beach choice. From October to December, the Gulf takes its heavy rain.
January to April is good on both coasts. Book villas and yachts early for Christmas, New Year and Chinese New Year. Our Andaman coast and Gulf coast guides explain each side.
The Department of National Parks opens the Similan Islands from 15 October 2026 to 15 May 2027. In the Gulf, Ang Thong Marine National Park near Samui is closed from 1 November to 15 December 2026. We plan routes around these dates.
The Andaman side: Phuket, Krabi, Phang Nga, Trang and Satun
On the Andaman side, limestone islands rise from emerald water. Phuket is the base for resorts, villas and yacht marinas. It is Thailand's largest island, by Department of Marine and Coastal Resources measurements.
Krabi has Railay's cliffs and the islands of Phang Nga Bay. Phang Nga, between Phuket and Krabi, holds the bay's most famous karsts and the quiet resorts of Khao Lak. Further south, Trang and Satun have quieter islands such as Koh Kradan and Koh Lipe.
Inland, Khao Sok offers rainforest, floating lodges and a great lake between limestone peaks. Add two nights there between Phuket and Krabi, and wake to mist on the lake at dawn.
Our yacht charter guide shows the routes from Phuket to Phang Nga Bay and Phi Phi.
The Tourism Authority of Thailand gives ฿400 for a foreign adult at Hat Noppharat Thara-Mu Ko Phi Phi National Park. Maya Bay closes every year from 1 August to 30 September, and swimming there is not allowed. Our call: sail early, and you reach Phi Phi before the day boats. Your captain handles the tickets and the mooring rules.
The Gulf side: Samui, Phangan, Tao and Hua Hin
The Gulf side is calmer and greener, with coconut palms and gentle seas. Koh Samui is its luxury base, one of Thailand's largest islands, with five-star resorts and an airport of its own. You land on the island, and your car is waiting; the airport opens from 06:00 to 22:00, so plan arrivals inside those hours. Koh Phangan and Koh Tao lie a short boat ride north.
Koh Phangan has quiet north-coast beaches as well as its parties, and Koh Tao is made for diving. On the mainland, Hua Hin is a royal seaside town within driving distance of Bangkok, with golf and long sandy beaches.
Cities of the south: Hat Yai, Surat Thani and Phuket Town
The south's main cities are Hat Yai, Surat Thani and Phuket Town. The Tourism Authority of Thailand calls Hat Yai the south's hub for transport, trade, tourism and education. Surat Thani is the gateway to Samui and Khao Sok.
Flights from Bangkok reach Hat Yai in about 1 hour 25 minutes, with Thai AirAsia, Thai Lion Air and Bangkok Airways. The State Railway of Thailand's train 31 leaves at 16:50 and arrives at 07:05. See our Hat Yai guide for the city's markets and food.
Pass through these cities rather than stay. The exception is Phuket Town, whose old shophouses, cafés and Peranakan food are worth an afternoon.
Is it safe to travel to southern Thailand?
Yes, the resort areas are safe for visitors. The UK Foreign Office's advice of 12 October 2026 covers only the far south, near the border with Malaysia.
It advises against all but essential travel to Pattani, Yala and Narathiwat, and to four Songkhla districts: Chana, Thepa, Na Thawi and Saba Yoi. Hat Yai lies in Songkhla but outside those four districts.
The UK also says attacks could happen anywhere in Thailand, including tourist areas, so take normal care. For full advice, read our safety guide.
At sea, we use licensed crews, check the weather each morning and change the plan when the sea is rough.
The tourist police take calls in English on 1155, and the ambulance service answers on 1669. Phuket has two JCI-accredited international hospitals in Phuket Town: Bangkok Hospital Phuket and Bangkok Hospital Siriroj.
Plan the south with Tanner
Tanner, your planner, plans the south by season and by coast. Tell us your month, your group and your style, and we get back to you right away. We match the coast to the weather, book the villa or resort, arrange the yacht days and handle every transfer between islands.
If your dates fall between seasons, we split the trip: a few nights on one coast, then a short flight to the other. Our Thai staff work on both coasts. Some famous islands are crowded by noon, so we plan your boat around them. We never share where you stay or who travels with you.
Example plan. A long February weekend, given as a sample. You wake in a pool villa above the Andaman, from ฿18,500 a day, and a private chef cooks from ฿11,500 a day. Day two is a crewed yacht to Phi Phi and Phang Nga Bay, priced to your plan. Then two nights at a floating lodge in Khao Sok, with a quiet boat ride across the lake. Prices are VAT included.
