Cambodia River Experiences

Glide the mighty Mekong, drift through floating villages on the Tonlé Sap, watch fireflies light the banks at Kampot and arrive in Phnom Penh by water — Cambodia is a country best seen from its rivers.

Life moves on the river

  1. 01

    The Mekong's richest stretch

    Cambodia sits where Southeast Asia's greatest river widens dramatically — feeding temples, silversmith islands and entire towns built on the water.

  2. 02

    The lake that flows backwards

    The Tonlé Sap is the only river on Earth that reverses twice a year, swelling the lake sixfold each monsoon — a hydrological wonder you can sail right into.

  3. 03

    Every budget floats

    From $200 day boats to the ultra-luxury Aqua Mekong, river travel here works at every level — and replaces long bus rides with scenery.

The river that reverses

Each monsoon the Mekong pushes the Tonlé Sap backwards, and the lake swells from 2,500 to over 16,000 km² — rising up to nine metres. It shapes everything you'll see on the water.

Mekong River Cruises

Cambodia's most prestigious water journey. Sail Siem Reap to Phnom Penh, or cross the border all the way to Ho Chi Minh City — stopping at the silversmith island of Koh Chen, the floating port of Kampong Chhnang and the royal hill of Udong. Vessels range from comfortable day boats to the 40-guest Aqua Mekong with a spa, plunge pool and fine dining.

Tonlé Sap Floating Village Tours

Whole communities — schools, pagodas, markets and ice factories — built entirely on water. Visit Kampong Phluk, where dry-season stilts soar 6–8 metres above the lakebed; the large, untouristed Kampong Khleang; accessible Chong Khneas; or remote Prek Toal for birdlife. A UNESCO Biosphere Reserve and a genuine window into a water-adapted way of life.

Cambodia river FAQ

How much does a Mekong cruise cost?
River travel spans every budget: day trips and 2–3 night segments run $200–500 per person, mid-range cruises $1,500–3,500, and ultra-luxury programmes such as the Aqua Mekong $6,500–14,000+ for 7–15 nights.
When can cruise ships reach the Tonlé Sap lake?
During high water season, roughly mid-August to November, the lake rises enough for ships to dock just 45 minutes from Siem Reap. In low water (December to mid-August) the lake is inaccessible to larger vessels, though the Mekong itself is calmer and clearer.
Which Tonlé Sap floating village is best to visit?
Kampong Phluk is famous for towering dry-season stilts; Kampong Khleang is the largest and least touristed; Chong Khneas is closest to Siem Reap; and remote Prek Toal is best for birdwatching and unspoiled village life.
Why does the Tonlé Sap flow backwards?
Each monsoon the Mekong's floodwaters push back up the Tonlé Sap River, reversing its flow and expanding the lake from about 2,500 to over 16,000 km², rising up to nine metres — a hydrological phenomenon found nowhere else on Earth.
Where can I see fireflies on a river in Cambodia?
Kampot's Preaek Tuek Chhu River is the signature firefly experience — sunset and after-dark cruises drift past mangrove banks lit by thousands of synchronous fireflies, best from November to April.
