This southwestern journey connects Phnom Penh with one carefully chosen Cardamom gateway and Koh Kong. It is a nature route that requires advance contact, weather flexibility and fewer fixed assumptions than a city itinerary. In return you get rainforest, rivers, mangroves and community-run tourism.
Days 1–2: Phnom Penh
Prepare cash, connectivity and any specialist equipment after arriving. Confirm the community or lodge transfer before leaving the city. Cash matters: ATMs and card payments are scarce once you leave the main road.
Days 3–6: Cardamom Mountains
Choose Chi Phat for community-organised activities or a confirmed lodge and river experience around another gateway. Do not attempt to combine distant areas merely because both use the Cardamom name.
Community
Chi Phat
A community-based ecotourism village reached by road and boat from Andoung Tuek on the Phnom Penh–Koh Kong road. Trekking, mountain biking, river trips and homestays are organised locally.
River lodges
Tatai
Floating and riverside lodges on the Tatai River, near the Tatai waterfall. Easier to reach and more comfortable, with kayaking and boat trips.
Conservation
Guided forest stays
Some conservation organisations run tented camps where your stay supports ranger patrols. Book ahead and follow their guidance on wildlife.
Read the Cardamom Mountains guide before choosing, and see ethical wildlife watching.
Days 7–8: Koh Kong
Use Koh Kong as a river-and-mangrove pause or transport base. Confirm border, boat and road details separately if continuing beyond the city.
Mangroves
Peam Krasop
A long boardwalk and viewing tower through the mangrove forest just outside town. Go in the morning or late afternoon.
Island
Koh Kong Island
Cambodia’s largest island, reached by boat day trips to quiet beaches. Trips depend on the sea and season.
Rest
A slow day
After the forest, a day in town to rest, do laundry and plan onward travel is worth building in.

Build for uncertainty
Rain, river levels and forest access can reshape the plan. Keep the final night outside the remote section before an important flight or border connection.
When to go
The drier months, roughly November to April, are best for trekking and roads. The Cardamoms receive very heavy rain from about June to October, when trails are muddy, leeches are common and some activities stop.
Frequently asked questions
Do I need to book Chi Phat in advance?
Yes. Contact the community tourism office or your lodge before leaving Phnom Penh to arrange transfers, guides and accommodation.
Can I cross into Thailand from Koh Kong?
The Cham Yeam–Hat Lek crossing is near Koh Kong, but land crossings with Thailand have been subject to closures. Check current official information and your visa requirements before planning to cross.
Is this route suitable for families?
Tatai’s river lodges and Koh Kong suit families well. Multi-day treks from Chi Phat are better for fit, experienced walkers.
