Fragile nature — stay on the trail, leave no trace.

A Cambodian crater lake so round its shore looks drawn with a compass, 800 metres across, ringed by forest the Tampuan hold as spirits' home.

September·Quiet month

May–Oct

Southwest monsoon turns the laterite road to slick red clay, though a moto still manages it. The lake stays emerald — no stream feeds it, so rain never muddies it — and nothing formally shuts. You simply lose the dry comfort and the dawn steam.

Year-round The emerald water and its ring of sacred Tampuan forest stand here every day; no stream feeds or drains the crater, so rain never clouds it. The dawn steam, heat and road are what change.

Yeak Laom is a crater lake in the far northeast of Cambodia so round that its shore looks drawn with a compass. It lies five kilometres out of Banlung, in Ratanakiri, eight hundred metres across and close to fifty deep, and no stream runs into it or out of it. Rain never muddies it, so the water stays clear for several metres whatever the season. Wooden jetties run out over a floor that drops away fast. You push off the boards, turn onto your back, and the ring of forest closes overhead in a circle. A path of about two and a half kilometres goes right round, mostly set back among the big trees rather than at the water's edge, with platforms opening onto the surface at intervals. It takes under an hour, and the far side is quiet enough to hear the forest over the swimmers. The road out from town is laterite so red it powders your shoes, past cashew groves and Tampuan villages, and in the dry months you arrive dusted orange. That red ground is the province's other story. Ratanakiri means gem mountain, and the basalt that blew this crater open carried up crystals of zircon from far below with it. Miners still sink narrow shafts by hand around Banlung, and heat turns the dull brown stones the vivid blue sold as gems. Nobody knows how old the hole is. The four thousand years repeated in guidebooks has no published source under it, the volcanic field itself dates back some seven hundred thousand years, and the crater has never been dated at all. The Tampuan have an answer of their own: a giant dug the pit to take his daughter back from a suitor, and the rain filled it. Their spirits live in the ring of trees, and the five villages around it run the lake themselves, with a small centre by the entrance where they tell it in their own words. That forest is still standing for the same reason the story is. To the people who own it, this was never scenery.

Worth knowing

Good to know

Be on a jetty at first light — the mist lifts within an hour of sunrise, and the water is yours before the families from Banlung arrive to swim.
Take the life jacket the community hands out — the crater floor falls away fast to nearly 50 metres, there are no lifeguards, and the swimming areas are the jetties, not the forest shore.
The five kilometres from Banlung are red laterite — dust in the dry months, slick clay in the rains. A tuk-tuk or motorbike manages it easily; walking it is a hot hour.
Weekends and holidays belong to Khmer picnickers — arrive on a weekday and the far side of the loop path stays quiet enough to hear birds over the swimmers.

Things to do

1
Float out where the forest rim closes in a circle
Wooden jetties run out over water that stays warm all year and drops away fast beneath you — nearly 50 metres at the middle. Push off the boards, turn onto your back, and the whole rim of forest closes in a circle above you.
2
Ride the red road out of Banlung
The five kilometres from town run on laterite so red it powders your shoes, past cashew groves and Tampuan villages. On a rented motorbike it takes a quarter of an hour, and in the dry months you arrive dusted orange.
3
Ring the lake through the trees, platform to platform
A path of about two and a half kilometres rings the entire lake, mostly back among the trees rather than at the water's edge, with wooden platforms opening onto the surface at intervals. It takes under an hour, and the far side is quiet enough to hear the forest over the swimmers.
4
Hear the lake's story from the Tampuan
The small cultural centre by the entrance belongs to the five villages that manage the crater. Inside are the everyday objects of Tampuan life — baskets, tools, gongs — and the account of how a community came to run the lake that its own spirits are said to inhabit.
