Sangkhlaburi travel guide: the Mon Bridge, the lake and border culture

Sangkhlaburi sits at the far western edge of Thailand, where three rivers meet in a vast reservoir surrounded by forested hills. Thai, Mon and Karen communities live on either side of the water, linked by the longest wooden bridge in the country. It is a long way from anywhere, which is exactly why the mornings here are so quiet.

Where to stay

Season and timing
Mid-October to mid-February is cool, sometimes misty in the mornings; the rainy season brings high water and slower roads.

The short answer

Give Sangkhlaburi two nights; the drive from Kanchanaburi town takes most of a morning. Walk the Mon Bridge at dawn, visit Wat Wang Wiwekaram and the Mon village across the water, and take a boat on the reservoir. Stay by the lake. You need a car or a minivan to get there, and a driver or tour for anything beyond the town.

Is the long trip worth it?

Sangkhlaburi is a destination in itself, not a day trip: the Ministry of Tourism and Sports' directory puts Wat Wang Wiwekaram about 220 kilometres from Kanchanaburi town, along winding mountain roads past the Vajiralongkorn Dam. Come if you want a slow, cool and culturally mixed corner of Thailand.

It is less suited to a short trip, to travellers who want beaches or nightlife, or to anyone who cannot spend most of a day travelling in each direction.

The Mon Bridge at dawn

The Uttamanusorn Bridge, known to everyone as the Mon Bridge, is described by the directory as the longest wooden bridge in Thailand at 850 metres. It crosses the Songkalia River between Sangkhlaburi town and the Mon village, and was built on the initiative of the revered monk Luang Por Uttama, using local labour and materials, to replace a bamboo raft crossing for which villagers paid a baht.

Walk it in the early morning, when mist lies on the water and local people cross on their way to market and temple. It is a working footbridge: keep to one side, do not jump or swing on it, and ask before photographing people up close.

Wat Wang Wiwekaram and the Mon village

Wat Wang Wiwekaram, also called Wat Luang Pho Uttama, stands on a hill in the Mon village across the bridge. The directory explains that it was founded in 1953 by Luang Por Uttama with Karen and Mon villagers, and remains the spiritual centre for the many communities of the district. Visit its chedi and halls in modest dress, and allow time for the morning market nearby.

When the reservoir is low in the dry season, the ruins of the old temple, flooded when the dam was built, may appear above the water; boat trips go there when the level allows. Ask locally whether they are visible before booking.

On the water and beyond town

The reservoir behind the Vajiralongkorn Dam (formerly Khao Laem Dam), completed in 1984, gives Sangkhlaburi its lakeside setting. Longtail boats can be hired from the waterfront for an hour or two on the lake, to the old temple ruins and the river channels where the Songkalia, Beekly and Rantee rivers meet.

The Three Pagodas Pass, about 20 kilometres further on at the border with Myanmar, marks an ancient crossing between the two countries; the directory lists it as open from 6:00 to 18:00. Treat it as a viewpoint and historical site rather than a border crossing — rules for foreigners crossing here are restrictive and change, so check official advice and do not plan a crossing.

Getting there

From Kanchanaburi town, Sangkhlaburi is reached by road along Highway 323 through Thong Pha Phum. Minivans run from Kanchanaburi; driving yourself or hiring a driver lets you stop at viewpoints and at Hellfire Pass on the way.

The mountain road is narrow and winding beyond Thong Pha Phum. Avoid driving it after dark, allow extra time in the rainy season, and fill up with fuel before the last stretch.

Practical questions

How far is Sangkhlaburi from Kanchanaburi?

Around 220 kilometres to Wat Wang Wiwekaram, according to the Ministry of Tourism and Sports' directory — most of a morning by road.

Is the Mon Bridge really made of wood?

Yes. The directory describes it as Thailand's longest wooden bridge, at 850 metres.

Can I see the sunken temple?

Only when the reservoir is low, usually in the dry season. Ask a boat operator in town whether it is visible.

Can I cross into Myanmar at the Three Pagodas Pass?

Do not plan to. Visit it as a viewpoint and historical site, and check official advice; crossing rules for foreigners are restrictive and change.

How long should I stay?

Two nights, so that you have one full day on the lake, the bridge and the Mon village.
