Tatai waterfall and the Cardamom Mountains

Two or three nights of river, rainforest and quiet

National parks and natureType
In short

Tatai waterfall is a wide, stepped waterfall on the Tatai river in Koh Kong province, about 20 km from Koh Kong town on National Road 48. It lies on the southern edge of the Cardamom Mountains, a 300 km range of rainforest that holds at least 62 globally threatened species. You can swim in its pools in the dry season, and riverside jungle lodges make it the easiest base for exploring the Cardamoms.

Tatai waterfall sits on the Tatai river in Koh Kong province, on the southern edge of the Cardamom Mountains, one of the largest and wildest rainforests left in South-East Asia. The falls are a broad set of rock shelves rather than a single high drop, and the river around them is lined with a handful of remote jungle lodges. It is the easiest way to spend a few nights inside the Cardamoms without a full expedition.

Most travellers race past Tatai on the bus between Phnom Penh, Sihanoukville and the Thai border. That is a shame. Slow down here and you get green river mornings, kayaks, forest walks and nights with little more than frogs and generators for company.

The Cardamom Mountains

The Cardamoms run for about 300 kilometres through south-west Cambodia and into eastern Thailand, from the Gulf of Thailand coast up towards Pursat. Their highest point, Phnom Aural at 1,813 metres, is also the highest mountain in Cambodia. The seaward slopes catch the full force of the monsoon, with 3,800 to 5,000 mm of rain a year, and that rain feeds dense evergreen forest.

The range is one of the most important wildlife refuges in the region. Wikipedia’s summary of survey work lists at least 62 globally threatened animal species, including Cambodia’s largest population of Asian elephants, clouded leopards, dholes and Siamese crocodiles, and more than 450 bird species. Tatai lies on the edge of Southern Cardamom National Park, protected in 2016 and covering 4,104 square kilometres.

Tatai waterfall and the river

The Tatai river is wide, deep and slow for most of its length, flowing out of the hills through forest and then mangroves to the sea. Near the old highway crossing, the riverbed steps down over a series of broad rock ledges, and that is Tatai waterfall.

In the dry season the water spreads thinly over the shelves, leaving warm pools and flat rocks for sitting and swimming. In the wet season it turns into a loud, brown, powerful torrent that is spectacular to watch and dangerous to enter. Either way, it is a pretty spot, framed by trees and quiet for most of the day.

You can reach the falls along a short track from the main road, or more memorably by boat from the Tatai bridge, a trip of about 20 minutes. The lodges upriver all run boats and will usually include the falls in a stay.

Things to do around Tatai

On the water

Kayaking the Tatai

Paddle the calm stretches above and below the lodges early in the morning, when mist lies on the river and kingfishers and hornbills are most active.

Swimming

The falls in the dry season

Between about December and April the rock pools at the falls make a lovely swim. Ask your lodge about current and water levels first.

Forest

Guided jungle walks

Lodges arrange half-day and full-day walks into the forest behind the river with local guides. Expect heat, humidity and leeches in the wet months.

Mangroves

Down to the estuary

Take a boat downstream to where the river meets the sea through mangrove channels, a good trip for birds and for the late-afternoon light.

Community

Chi Phat ecotourism

Further east, the village of Chi Phat runs a community-based ecotourism project with support from Wildlife Alliance, offering homestays, treks and cycling in the Cardamoms.

Nearby

Koh Kong and Peam Krasop

Koh Kong town is 20 to 30 minutes away. The mangrove boardwalk at Peam Krasop and boat trips to the Koh Kong islands are easy additions.

Best time to visit

Koh Kong is one of the wettest parts of Cambodia, so the season matters more here than almost anywhere else in the country.

  • November to April (dry season): the best time overall. Rivers are calm and clear, trails are walkable and the falls are safe for swimming in the pools. Late in the season the waterfall flow is much lower.
  • May to October (wet season): very heavy rain, especially from July to September. The forest is at its greenest and the waterfall at its most dramatic, but swimming is out and some trails and boat trips may not run.
  • Time of day: mornings for wildlife and paddling; late afternoon for the mangroves and the sunset.

How to get there

Tatai is on National Road 48, the road that links Sre Ambel and the Sihanoukville area with Koh Kong town and the Cham Yeam border crossing into Thailand. The village and bridge are about 20 kilometres before Koh Kong town.

From Koh Kong town About 20 km by road, 20 to 30 minutes
From Phnom Penh A long day on the road, five to six hours by private car; buses stop at Tatai on request
From Sihanoukville or Kampot Allow three to four hours by car
From the Thai border Cham Yeam is just beyond Koh Kong town, under an hour away
To the lodges By boat from the Tatai bridge landing; lodges arrange pick-ups

If you are travelling by bus, tell the driver you want to get off at the Tatai bridge and let your lodge know your arrival time. A private car with driver is much easier, especially if you want to combine Tatai with the coast.

Practical information

Waterfall entry Access is informal; a small local fee may be collected at the road entrance, so confirm locally
Opening hours Daylight hours
Time needed Two to three hours for the falls; two nights to enjoy the river

Phone signal Patchy on the river, which most guests come to enjoy
Our advice

  • Stay at least two nights. The journey is long, and the magic of the river is in the quiet mornings, not a quick photo stop.
  • Pack for the forest. Light long trousers, long socks or leech socks, closed shoes, insect repellent and a dry bag for boat trips.
  • Treat the falls with respect. Do not swim when the river is high or brown. Currents over the ledges are much stronger than they look.
  • Bring cash and a torch. Many lodges run on solar power or generators, and paths are dark at night.

Visiting responsibly

The Cardamoms are under real pressure from land clearing, sand dredging on the rivers and illegal hunting. Staying at locally run lodges, hiring local guides and joining community projects such as Chi Phat puts money into keeping the forest standing.

Please do

  • Use local guides for forest walks
  • Take all your rubbish back out with you
  • Keep noise down on the river at dawn and dusk
  • Choose lodges that treat water and run on solar
Please don’t

  • Buy wild meat, animal parts or orchids from the forest
  • Feed or approach wild animals
  • Use soap or shampoo in the river
  • Walk off trail without a guide

A suggested two nights

  1. Day 1, afternoon Arrive at the Tatai bridge, boat to your lodge, swim and settle in
  2. Day 1, sunset Boat downstream to the mangroves and the river mouth
  3. Day 2, dawn Kayak on the misty river while the birds are active
  4. Day 2, late morning Guided forest walk and a visit to Tatai waterfall
  5. Day 2, afternoon Rest in the heat, or a boat trip to a second set of falls
  6. Day 3 Continue to Koh Kong and Peam Krasop, or head back towards the coast

Tatai fits well with the rest of the south. Many travellers come here from the islands of Koh Rong and Koh Rong Sanloem, or pair it with Bokor National Park near Kampot. See our wildlife experiences and river experiences for more ideas.

Questions travellers ask

Where is Tatai waterfall?
It is on the Tatai river in Koh Kong province, south-west Cambodia, about 20 km from Koh Kong town along National Road 48. It sits on the southern edge of the Cardamom Mountains.
How do I get to Tatai from Phnom Penh?
Drive or take a bus towards Koh Kong on National Roads 4 and 48; by private car it takes five to six hours. Ask the bus to stop at the Tatai bridge, where the river lodges collect guests by boat.
Can you swim at Tatai waterfall?
Yes, in the dry season, roughly December to April, in the pools between the rock shelves. In the wet season the current is strong and swimming is dangerous.
Is there an entrance fee for Tatai waterfall?
Access is informal and a small local fee is sometimes collected at the road entrance. Confirm locally, and bring small US dollar notes.
How long should I stay in Tatai?
At least two nights. The journey is long, and the best of Tatai is the quiet river mornings, kayaking and forest walks rather than a quick stop at the falls.
What are the Cardamom Mountains?
A range about 300 km long in south-west Cambodia and eastern Thailand, covered in dense rainforest. It includes Phnom Aural, Cambodia's highest peak at 1,813 metres, and is one of the most important wildlife refuges in South-East Asia.
What wildlife lives in the Cardamom Mountains?
At least 62 globally threatened animal species, including Asian elephants, clouded leopards, dholes, sun bears, pangolins and Siamese crocodiles, plus more than 450 bird species. Most are shy, so sightings are rare.
When is the best time to visit the Cardamom Mountains?
November to April, when rivers are calm and trails are dry. Koh Kong is one of the wettest parts of Cambodia and the rains from July to September are especially heavy.
Is there an ATM in Tatai?
No. Bring enough US dollars from Koh Kong or Phnom Penh for your stay, tips and activities.
What is Chi Phat?
A community-based ecotourism project in the southern Cardamoms, run by the village with support from Wildlife Alliance. It offers homestays, guided treks and cycling.
