Plan around one fact: Amphawa Floating Market runs Friday, Saturday and Sunday afternoons and evenings only. A midweek visit gets you a quiet canal town with good cafés — pleasant, but not the place in the photographs. The Maeklong Railway Market operates daily around the train times, and the firefly boats are evening, seasonal and weather-dependent. Confirm times locally before travelling.
What to see
Maeklong Railway Market (Talat Rom Hup)
Tambon Mae Klong, Mueang Samut Songkhram — immediately east of Maeklong railway stationThe umbrella-pulldown market, and one of the largest fresh seafood markets in Thailand. The stalls are laid out directly on and over the railway track. Whenever a train approaches, the awnings and shop fronts are pulled back from the rails and replaced the moment it has gone — eight times a day, because four trains run each way on the Ban Laem line. The station behind it is a class 1 station opened on 10 June 1905 in the reign of King Chulalongkorn, and is the main station of the province. This is the single image most people outside Thailand associate with Samut Songkhram, and it is a working market rather than a display: come early, expect fish, and stand where the locals stand.
Amphawa Floating Market
On the canals beside Wat Amphawan Chetiyaram, Amphawa districtAn afternoon and evening food market on the water, and — crucially — it runs on Fridays, Saturdays and Sundays only. Anyone judging Amphawa by a Tuesday visit will get a completely different town from the one in the photographs. Boat vendors cook to order from the water while visitors eat from the canalside; the surrounding wooden shophouses have been restored as cafés, guesthouses and shops. Five hundred metres from the market sits Chuchai Buri Sri Amphawa, a billion-baht complex with an 18-room hotel, shopping, a restaurant and a Hindu shrine, built by the gemstone dealer and designer Chuchai Chairitthilert in an unrestrained mix of Thai traditional and neoclassical.
King Rama II Memorial Park
Beside Amphawa Floating Market, Amphawa districtFour traditional Thai houses arranged in an ethnology style on the birthplace of King Buddha Loetla Nabhalai, Rama II, displaying the art, artefacts and daily life of the early Rattanakosin era. He was born here while his father served as governor of Ratchaburi — in 1766 by the district's own account and 1767 by the province's, and we print both rather than settle it. His mother, Queen Amarindra, consort of Rama I, was born in Amphawa too. The Celebrations of King Rama II are held here every early February, the month of his birth.
The firefly boats
The Amphawa waterways, after darkEvening boat trips around the canals to see fireflies in the lamphu trees along the banks — one of the two things, alongside the floating market, that turned Amphawa into a Bangkok weekend destination. It is a seasonal and weather-dependent spectacle rather than a guaranteed one, and it depends on the health of the riverside trees the insects breed in, so ask locally about conditions rather than booking blind.
Don Hoi Lot
The sandbanks off the coast of Mueang Samut Songkhram districtThe sandbar at the mouth of the Mae Klong, famous for its population of the razor shell Solen regularis, and listed as a Ramsar wetland of international importance since 2001. It is the first thing named in the provincial slogan — City of razor shells — and it is best at low tide, when the flats are exposed and the shells are collected. Around it are the salt pans that make this province a leader in Thai sea-salt production, worked in the last figure we could open across 4,535 rai by 111 households.
Wat Phet Samut Worawihan (Wat Ban Laem)
Tambon Mae Klong, Mueang Samut SongkhramThe temple that holds Luang Pho Ban Laem, the Buddha image named in the last line of the provincial slogan. The bathing and worship ceremony is held every mid-April at Songkran and is the province's principal religious event alongside the Rama II celebrations. The Mae Klong ferry pier sits beside the temple, on a river that bisects the province.
Khai Bang Kung and Wat Bang Kung
Tambon Bang Kung, Bang Khonthi districtA river fort of the late Ayutthaya and Thonburi periods, and the reason King Taksin the Great matters to this province: when the Burmese reached Bang Kung he gathered the people to build a fort and hold the town. Deserted for nearly two centuries, the site became a Boy Scout camp in 1967 and now carries a shrine commemorating the king. Wat Bang Kung stands in the same tambon. The district's principal temple, Wat Charoen Sukharam Worawihan, holds Luang Pho Toa — a laterite-cored image, plastered and gilded, in the Sukhothai style.
Nativity of Our Lady Cathedral, Bang Nok Khwaek
Bang Nok Khwaek, Bang Khonthi districtBuilt in 1890 in French Gothic style, and the seat of the Roman Catholic Diocese of Ratchaburi — a cathedral in an orchard district of a few thousand people, and one of only two Christian churches in the province. There is a second Catholic church at tambon Bang Yi Rong. Samut Songkhram is unusual in holding places of worship of three major religions in a very small space: well over a hundred Buddhist temples, these two churches, one mosque, and what is described as the oldest Chinese joss house and almshouse in Thailand, over 215 years old.
Tha Kha Floating Market
Tambon Tha Kha, Amphawa districtAmphawa's quieter sibling: smaller, on a traditional schedule rather than a weekend one, and the market Thai visitors recommend when they want to show you what the canals were like before the tour buses. Tha Kha is the district's largest subdistrict on the figures we could read, at 5,570 people. The orchard country around it — lychee, pomelo and coconut — is the source of the second line of the provincial slogan and of the coconut palms on the provincial seal.
Wat Bang Kae Yai and Wat Bang Kae Noi
Amphawa district, on and near the Mae KlongTwo temples founded by the senior and junior wives of Chao Phraya Surasak. Wat Bang Kae Noi, on the Mae Klong, is built of golden teak carved with the biography of the Buddha by craftsmen and sculptors from Phetchaburi, a job said to have taken around a decade, and it holds a statue of Somdej Toh that draws its own pilgrims. The communities along Khlong Bang Kae around them run agricultural and cultural tourism, with resorts and guesthouses of their own.
Siamese Cat Village
Amphawa districtA traditional Thai wooden house given over to exhibits on the surviving Siamese cat breeds — Wichien Maat, Korat, Suphalak and Korn Ja, with Khao Manee included — numbering more than 130 exhibits, plus a good many live cats around the house and garden and a coffee shop. It was run by a kamnan, a community leader, who has since died; the house remains open. Admission is free with donations encouraged. The source we opened records as many as 800,000 visitors a year, mostly foreign, which is a striking figure for a wooden house in an orchard district and one we pass on with its provenance attached rather than as a verified count.
The Siamese twins
Mueang Samut Songkhram districtChang and Eng Bunker, the conjoined twins whose fame gave English the phrase Siamese twins, were born in this province on 11 May 1811. They were exhibited internationally from 1829, settled in North Carolina, took the surname Bunker, married and raised large families; their descendants have travelled back here for commemorations. A memorial park in the province marks the connection.
Pla thu Mae Klong, and the three kings porridge
The province's most famous product is a fish. Pla thu — short mackerel — from these waters is regarded as the best in Thailand, because the Bay of Bangkok is rich in the plankton the species feeds on, which gives the Mae Klong fish their size and their flavour. They are distinctive enough that Thais describe them by the shape the steaming basket imposes: na ngo kor hak, curved face, broken neck. Local cooking runs from pla thu tom madan, a spicy-sour soup, through chu chee pla thu in red curry sauce, to pla thu sa tia in a sweet black broth, and even to a mackerel burger you will not find anywhere else. The legendary dish is khao tom sam kasat, three kings porridge — a congee of mackerel, prawn and fresh squid said to have been devised by King Rama V himself during a visit to Mae Klong, and recorded as having been praised by Prince Damrong Rajanubhab as the best he had eaten anywhere. The Mackerel Festival is held at the Provincial Hall in November or December.
Samut Songkhram things-to-do FAQ
What is the one thing to see in Samut Songkhram?
The Maeklong Railway Market, if you only have an afternoon. It is a working fresh-seafood market laid out directly over a live railway track immediately east of Maeklong station, and eight times a day — four trains each way on the Ban Laem line — the stallholders pull the awnings back and lift the produce clear, then put everything back the moment the train has passed. It is one of the largest seafood markets in Thailand and it is not staged for visitors; it is how the market has worked since the line opened in 1905. If you have a weekend rather than an afternoon, pair it with Amphawa on a Friday, Saturday or Sunday for the floating market, the King Rama II Memorial Park and the firefly boats after dark.
When does the Amphawa floating market actually run?
Friday, Saturday and Sunday only, in the afternoon and evening, on the canals beside Wat Amphawan Chetiyaram. This is the single most important practical fact about the province for a visitor and it catches people out constantly. Midweek Amphawa is a quiet canal town with restored wooden shophouses and cafés — pleasant, but not the place in the photographs. The firefly boats also run in the evening and are seasonal and weather-dependent, so ask locally rather than booking blind. Tha Kha Floating Market nearby runs on a traditional schedule rather than a weekend one and is the smaller, quieter alternative.
Is there anything to do that is not a market?
A surprising amount for 416.7 square kilometres. Don Hoi Lot's razor-shell sandbanks are a Ramsar wetland of international importance, listed in 2001, and best at low tide; the salt pans behind the coast are a landscape in their own right. Khai Bang Kung in Bang Khonthi is the river fort where King Taksin held the line against the Burmese, now with a shrine to him. The Nativity of Our Lady Cathedral at Bang Nok Khwaek, built 1890 in French Gothic style, is the seat of the Roman Catholic Diocese of Ratchaburi. Wat Bang Kae Noi is a golden-teak temple carved with the life of the Buddha by Phetchaburi craftsmen. And the Siamese Cat Village is a wooden house full of exhibits on the surviving Thai cat breeds, with live cats and a coffee shop.
What festivals are worth planning around?
Four, and they are spread across the year. The Celebrations of King Rama II are held every early February at the King Rama II Memorial Park in Amphawa, in the month of his birth. The worship and bathing of Luang Pho Ban Laem takes place every mid-April at Wat Ban Laem, falling in Songkran. The Mackerel Festival is held at the end of the year, in November or December, at the Provincial Hall, to promote the eating of pla thu Mae Klong. And Loy Krathong here is genuinely distinctive: krathongs are made from banana leaf-sheaf — kab kluai — rather than the usual trunk sections, and dressed with locally famous long-burning incense, at Wat Phumarin Kudi Thong by the river. There is also an annual lychee fair.
Why is the mackerel such a big deal here?
Because it is genuinely different, and the province has built a food identity on it. Pla thu Mae Klong — short mackerel from these waters — grows large and rich because the Bay of Bangkok is thick with the plankton the fish feed on, and it is recognisable enough that Thais describe it by the shape the steaming basket gives it, curved face, broken neck. It appears in a whole family of local dishes, from spicy-sour soup to red curry to a sweet black broth, and even in a mackerel burger you will not find elsewhere. The province's most legendary dish is khao tom sam kasat, three kings porridge, a congee of mackerel, prawn and fresh squid said to have been devised by King Rama V himself on a visit to Mae Klong, and praised by Prince Damrong Rajanubhab as the best he had eaten anywhere.
