Areng Valley: nature and community in the Cardamoms
The Areng Valley is a remote corner of the Cardamom Mountains known for clear rivers, Siamese crocodiles and Chong communities. Here's what to know before you go.
In this guide
The Areng Valley lies deep in the Cardamom Mountains, where the Areng river winds through forest and small villages. It is one of the most remote places that travellers can reach in Cambodia, and one of the most rewarding for those who want quiet nature and community life.
The valley
The Areng river flows through a landscape of forested hills, rocky rapids and farmland. Villages along its banks are home to communities including the Chong people, who have lived in the area for generations and have close cultural ties to the forest.
Wildlife
The valley is important for wildlife. It is one of the few places where the critically endangered Siamese crocodile still lives in the wild. Other species include the Asian arowana, a rare fish, along with gibbons, hornbills and other forest animals. Seeing crocodiles is rare; their presence is a sign of a healthy river.
A valley in the spotlight
In the 2010s, plans for a hydropower dam in the valley drew national attention, as it would have flooded villages and important habitat. The project was put on hold after opposition from local communities, conservation groups and activists. The area remains part of the Cardamoms' protected forest network.
What to do
- River trips by small boat or kayak.
- Treks through forest and along the river with local guides.
- Homestays in villages, learning about farming and forest life.
- Birdwatching in the early morning.
Getting there
Access is via rough roads from the main highway between Koh Kong and Phnom Penh, usually by four-wheel drive or dirt bike. The journey can be difficult in the rainy season. Most visitors go with an experienced operator who can arrange transport, guides and homestays.
Visiting responsibly
- Travel with local guides or community-based programmes.
- Respect local customs and ask before photographing people or sacred places.
- Keep group sizes small.
- Take all rubbish out with you.
When to visit
The dry season, roughly from November to April, makes travel much easier. In the rainy season, the river is high and the roads are challenging.
What to bring
Cash, a head torch, insect repellent, sun protection and clothes for both river and forest. Expect no ATMs and little or no phone signal.
