Chumphon

Chumphon is a provincial town on the Gulf coast of southern Thailand, best known as the mainland port for boats to Koh Tao, but it is worth a night or two in its own right. Its beaches, led by Thung Wua Laen, had some of the cleanest coastal water in Thailand in the 2025 government tests, the islands of Mu Ko Chumphon National Park are offshore, and the fishing village of Koh Phithak takes guests in homestays.

Most travelers arrive in Chumphon on a night train or bus and are on a catamaran to Koh Tao a few hours later. If you have a day to spare before or after the islands, you get a quieter Thailand: long beaches used mainly by Thai families, seafood at local prices and a town where tourism is a sideline. This guide covers what to see, where the sea is clean, the national park and how to make Chumphon work as a stopover.

Thung Wua Laen and the beaches of Chumphon

Hat Thung Wua Laen is Chumphon's best-known beach, and TAT chose it for a beach and underwater clean-up in 2018, together with the nearby islands of Ko Ngam Yai and Ko Ngam Lek. The Pollution Control Department's 2025 results placed it fourth in the whole country for coastal water quality, and another Chumphon site, Ao Sapli, came first. Our page on beach water quality in Thailand explains how the tests work and what the ratings mean; the short version is that Chumphon's results were among the best in the country.

Thung Wua Laen is not the only option. In a 2017 feature the Tourism Authority of Thailand (TAT) named Thung Zang Bay, Mo Bao beach and the Laem Thong cape as places with uncrowded beaches from May to October, and it also mentions Sai Ree beach. These are not resort strips, so expect fewer facilities than in Hua Hin or on the islands.

As anywhere on the Gulf, box jellyfish are occasionally reported in the rainy season; TAT's 2025 safety advice lists Koh Tao in Chumphon province among the places with sightings. Our guide to jellyfish in Thailand explains the warning signs and first aid.

Koh Phithak: a night in a fishing village

Koh Phithak (TAT spells it Pitak) is a small island fishing village off Bang Nam Chuet sub-district in Lang Suan district. TAT describes the village homestay as well known in the province and as a model of sustainable community-based tourism, with villagers living in stilt houses over the water. Under the national homestay standard, guests sleep under the same roof as the host family, which makes it a way of seeing the coast that a resort cannot offer.

At the very low tides of June a sandbar connects the shore with the island, and TAT has promoted an annual Lang Suan mini-marathon that finishes with a run through water about 30 cm deep to Koh Phithak. At other times you need a boat. We could not confirm 2026 booking contacts or prices for the homestay from an official source; the TAT Chumphon office (tel. +66 77 501 831-2 in TAT's 2018 release) is the place to ask. Our guide to homestays in Thailand explains how community homestays are registered, what a stay usually includes and how to be a good guest.

Mu Ko Chumphon National Park

The islands offshore are protected as Mu Ko Chumphon National Park. In April 2026 the Department of National Parks (DNP) named islands such as Ko Ngam Noi, Ko Ngam Yai, Ko Thalu, Ko Mattra, Ko Lawa and Ko Lak Raet, with hard and soft corals, lionfish and rays. TAT also notes the park's kayaking. If you book a boat trip to the islands, check that the park fee is included and that there are life jackets on board.

Mu Ko Chumphon is a Category 2 park: 200 baht for a foreign adult and 100 baht for a child. The DNP asks visitors not to step on or touch coral, not to feed fish, to take all litter home and to use reef-safe sunscreen; certain sunscreen ingredients are banned in marine parks, as our page on the sunscreen ban explains.

The islands usually close every year from 1 November to 15 December, during the northeast monsoon. TAT's published DNP closure lists for 2018 and 2023 both give those dates. We found no notice for the 2026 season yet, so check with the park before you book a boat in late October, November or early December.

The night market and eating in town

TAT's attraction page (archived 2021) describes the night market in the center, not far from the station, with stalls of Thai food, seafood, fruit and shakes, open every day from 18:00 to 23:00. It is the easiest dinner if you arrive in the evening or are waiting for a late train; our beginner's guide to Thai night markets explains how ordering works.

The province grows Robusta coffee, including at Khao Thalu, and TAT has promoted a Chumphon Robusta Coffee Fest in recent years; our guide to Thai coffee and tea explains the difference between the southern Robusta and the northern Arabica. TAT's southern fruit calendar also lists the Hom Thong Lamae banana as one of Chumphon's registered local products.

A night before or after the Koh Tao boat

Chumphon is where most boats to Koh Tao leave the mainland, and our guide to getting to Koh Tao has the piers, catamarans and through-tickets; this page does not repeat them. The case for staying a night is simple. Night trains from Bangkok reach Chumphon between about 22:00 and 05:30, and a sleeper that arrives at 04:00 leaves you waiting hours for a morning boat. Coming back, the island boats reach the mainland in the afternoon, and the overnight trains north do not leave until the evening.

A night in town or at Thung Wua Laen turns that dead time into a beach afternoon. It also helps when the sea is rough: if boats are cancelled, you are not stuck at the pier with a train to catch. If you have come down from Hua Hin, our page on Hua Hin to the Gulf islands covers the trains south. Divers heading for sites such as Chumphon Pinnacle will find the courses and schools in our guide to learning to dive on Koh Tao.

Getting to Chumphon by train, plane or road

By train. Southern trains leave Bangkok from Krung Thep Aphiwat Central Terminal. A secondary timetable source showed one day train in October 2026, special express 43, leaving at 07:30 and arriving at 13:50, plus about nine evening and night trains that arrive between 22:17 and 05:22. Northbound, special express 40 leaves Chumphon at 11:18 and reaches Bangkok at 18:05, and the night trains leave between about 20:50 and midnight. The State Railway's D-Ticket app has the official times; our guides to sleeper trains and train bookings online help with classes and tickets.

By air. Chumphon Airport (CJM) has flights to Don Mueang only. A departure board we checked for Tuesday 27 October 2026 showed Thai AirAsia at 09:00 and 15:40, and Nok Air had an evening flight at 19:30 the day before. Our page on domestic flights explains the airlines and baggage rules.

By road. North of Chumphon, the quieter beaches of Prachuap Khiri Khan and Ban Krut make good stops on the way down from Hua Hin. For a full driving route along this coast, drivinginthailand.com covers the road south in detail, and our guide to renting a car in Thailand has the licence and insurance rules.

When to go to Chumphon

Thai Meteorological Department averages for 1991–2020 show a warm, even climate: January averages a high of 30.8 °C and a low of 21.9 °C. The driest month is February, with 52 mm of rain, and the wettest are October (247 mm) and November (259 mm), when the northeast monsoon reaches the Gulf. That is the opposite of Phuket and the Andaman coast, which are wettest from May to October; our page on the best time for the Thai islands compares the two seas.

For beaches and the marine park, February to September is the best period. After the southern floods of late 2025, TAT reported in December that Chumphon was fully accessible again, but it also warned that boats can change their schedules in bad weather, so build in a spare day in the rainy months.

Frequently asked questions

Is Chumphon worth staying in, or just a ferry stop?

It is worth a night or two if you like quiet beaches. Thung Wua Laen had some of Thailand's cleanest coastal water in the 2025 government tests, the marine park islands are offshore, and a night in town makes the Koh Tao boat connection much easier, especially after a night train.

How long is the train from Bangkok to Chumphon?

The day train, special express 43, was scheduled to leave Krung Thep Aphiwat at 07:30 and arrive at 13:50 in October 2026, about six hours twenty minutes. Night trains take roughly six and a half to eight hours. Check the times in the D-Ticket app before booking.

When are the Mu Ko Chumphon islands closed?

The national park's islands are usually closed from 1 November to 15 December each year, during the northeast monsoon, according to TAT's DNP closure lists. No notice for 2026 had been published when we checked, so confirm with the park before booking a trip.

Can you walk to Koh Phithak?

Only at the very low tides of June, according to TAT, when a sandbar links the shore and the island. At other times you cross by boat. The village runs a community homestay; ask the TAT Chumphon office for current contacts.
