The Gulf of Thailand coast here stretches from Hua Hin south of Bangkok, via Chumphon and Surat Thani, down to Songkhla. It includes beach resorts like Hua Hin, tranquil fishing villages, and the island group of Koh Samui, Koh Phangan, and Koh Tao.The beaches are mostly shallow, and the sea is calmer than on the Andaman Coast. Important for planning: The southern Gulf receives most rain from October to December, which is when the season starts on the Andaman Coast. In May and June, it's the opposite, making the Gulf the better choice.Trains, buses, and highways run parallel along the coast. You can reach the islands by ferry from Chumphon, Surat Thani, and Don Sak.
The region encompasses the coast from Hua Hin to Songkhla and the islands in the Gulf. Koh Samui is the largest and most developed island, Koh Phangan is known for the Full Moon Party and quiet coves, Koh Tao for diving courses. On the mainland, Hua Hin has been a royal summer retreat since the 1920s. Further south are the Ang Thong Marine National Park, Khao Sam Roi Yot National Park, and ancient temple cities like Nakhon Si Thammarat. The driest period is usually from February to June.

Ang Thong Marine National Park
The Ang Thong Marine National Park comprises 42 islands in the Gulf of Thailand, located approximately 30 kilometers northwest of Koh Samui. Established in 1980, it spans over 100 square kilometers, with about half of that being land.
Hua Hin is one of Thailand's oldest seaside resorts, closely linked to the royal family. It features a long sandy beach, the historic train station with its royal pavilion, and, near the coast, the summer palaces Klai Kangwon and Mrigadayavan.
Koh Samui, Thailand's second-largest after Phuket, is the Gulf's most developed, with its airport, ring road, and lodging from basic bungalows to large resorts. The east coast (Chaweng, Lamai) drives tourism; the south and mountainous, palm-filled interior is calmer. Beyond beaches, the Big Buddha, Wat Plai Laem temple, and island waterfalls merit a visit. Planning note: Samui's rain patterns differ from the Andaman Coast, with most rain from mid-October to early December.
Koh Tao is the smallest of the three well-known islands in the Gulf of Thailand and thrives mainly on diving. Short boat rides to dive sites and numerous dive schools make the island one of the world's most important locations for dive training.The main arrival point is the pier of Mae Haad; the largest area is along the long Sairee Beach on the west coast. To the south, Chalok Baan Kao is quieter, while in the east, rocky bays can be reached via steep tracks.Notable dive sites include Chumphon Pinnacle, where lucky divers may spot whale sharks, most likely in April and May, and the rock Sail Rock between Koh Tao and Koh Phangan. In Shark Bay to the southeast, blacktip reef sharks can be observed while snorkeling.Northwest lies Koh Nang Yuan, three rocky islets connected by sandbars. Ferries operate from Chumphon, Koh Phangan, and Koh Samui; however, crossings are occasionally cancelled due to strong winds.

Street Art on the Kromluang Road (Chumphon)
On Krom Luang Road in Chumphon, artists have painted the walls of an entire street of houses. The motifs reflect what sustains the province: fishing, agriculture, and the sea off its coast. For most travelers, Chumphon is merely a transfer point for ferries to Ko Tao, and these murals offer one of the few reasons to see the city itself. The walk takes less than an hour.
Freshwater lake at the northern end of Songkhla Lagoon in Phatthalung Province. The wetland was declared Thailand's first Ramsar site in 1998. Take longtail boats in the early morning through fields of red water lilies, which bloom from mid-February to April and close by late morning. You'll see most birds from January to April.
Significant temple in Southern Thailand in Nakhon Si Thammarat. The bell-shaped, Sri Lankan-style chedi was built in the early 13th century and is 78 meters high, including its spire. At its base stand 22 stucco elephants. Since 2012, the complex is on the UNESCO World Heritage Tentative List. In the Wihan Kien, a museum displays Buddha figures and votive offerings.
A street stall in Chumphon selling fried bananas – kluai thot, one of the country's most popular snacks. The bananas are coated in batter and sold fresh from the oil, eaten standing up or on the go. It's nothing more than a roadside counter, and nothing more is needed.
A noodle soup spot serves portions in coconut shells – a detail its Thai name alludes to. The shells hold less than a standard bowl, so several rounds are ordered. Diners season at the table with chili, fish sauce, sugar, and vinegar. The decor is simple, the clientele local.
A stall at the market by the City Pillar Shrine, specializing in Tom Yum noodle soup – spicy and sour instead of clear broth. You eat at simple tables right in the middle of the market's hustle and bustle. As is common, you choose your noodle type and toppings yourself and season to taste at the table. It's busiest in the morning when the market is open.
An eatery on the Gulf Coast serving Thai cuisine with a focus on fish and seafood. The decor is simple and open, typical for the coast. Guests are predominantly locals; the menu is not tailored for travelers.
A street food stall specializing in Khao Na Gai: chicken in a thick sauce over rice, a dish with a distinctly Chinese influence. Portions are small to medium-sized, for quick, casual meals. The setup consists of a few tables next to the counter, the clientele comes from the neighborhood.
Die Küche der Golfküste ist südthailändisch, also schärfer und salziger als im Zentrum, arbeitet aber stärker mit Fisch aus dem flachen Golf als mit den großen Meeresfrüchten der Andamanenseite. Kokospalmen prägen die Landwirtschaft, besonders um Surat Thani und auf Ko Samui, entsprechend viel Kokosmilch und Kokoszucker landet in den Töpfen. Je weiter Du nach Süden kommst, desto stärker wird der malaiisch-muslimische Einfluss.
Khao Mok and Muslim cuisine of the South
In Songkhla, Hat Yai, and the border provinces, find spiced rice with chicken or goat, plus curries featuring cinnamon, cardamom, and star anise. The cuisine clearly differs from Central Thai.
Fried chicken from Hat Yai
Kai Thot Hat Yai is fried chicken with crispy shallots, named throughout Thailand after the city. It comes with sticky rice and a spicy dipping sauce.
Coconut from Surat Thani
Surat Thani and Koh Samui are major coconut-growing regions in the country. Beyond fresh coconut water, you'll find coconut sugar, sweets, and dishes with coconut milk.
Fish and Cuttlefish caught in the Gulf
In the fishing towns from Prachuap across Chumphon to Songkhla, fish, squid, and mussels are affordable. Common are grilled squid on a skewer, steamed fish with lime and chili, and Pla Thu, steamed mackerel in small bamboo baskets.
Khanom Jeen with Southern Thai Curries
Spicy curry with rice noodles, fresh herbs, cucumbers, and beans. The South usually adds a turmeric fish curry. A typical market and small shop breakfast.
History and Culture
The southern Gulf coast was early connected to maritime trade between India and China. In Chaiya near Surat Thani, temples like Wat Phra Borommathat recall the Srivijaya Kingdom era. Nakhon Si Thammarat was a religious center for centuries; its large chedi dates from the 13th century.From the 1920s, Hua Hin became a royal seaside resort when the Klai Kangwon Palace was built there. In Surat Thani, the Chak Phra festival is celebrated at the end of Buddhist Lent, with Buddha figures paraded through town on decorated floats and boats. Further south, around Songkhla, Muslim cuisine and culture become more visible.
Exploring Locally
Rail, bus, and highways run parallel along the coast heading south. The Southern Line from Bangkok travels via Hua Hin, Prachuap Khiri Khan, Chumphon, and Surat Thani to Hat Yai. The night train arrives in the morning; buses are often faster but less comfortable.From Bangkok, you'll need about three to four hours to reach Hua Hin, around seven to Chumphon, and nine to eleven to Surat Thani. Airports are located in Hua Hin, Chumphon, Surat Thani, Nakhon Si Thammarat, Hat Yai, and Koh Samui, among others.Ferries to the islands: from Chumphon to Koh Tao; from Don Sak and Surat Thani to Koh Samui and Koh Phangan. Separate connections operate between the three islands; combination tickets for train or bus plus ferry are common.Local transport: Songthaews and motorbike taxis in the towns. On the islands and in Hua Hin, scooters or rental cars are most practical.In the Southern Gulf, most rain falls from October to December, extending partly into January around Nakhon Si Thammarat and Songkhla. The driest period is usually from February to June.Current safety and health information, including for the southern border provinces, can be found at the Auswärtigen Amt.
