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.
Cambodia sits where Southeast Asia's greatest river widens dramatically — feeding temples, silversmith islands and entire towns built on the water.
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.
From $200 day boats to the ultra-luxury Aqua Mekong, river travel here works at every level — and replaces long bus rides with scenery.
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.
The water-based experiences travellers book most across Cambodia.

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.

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.

Available in every major city. Watch the illuminated Royal Palace from the Mekong–Tonlé Sap confluence in Phnom Penh; drift the lake under a pink sky in Siem Reap; chase synchronous fireflies along Kampot's mangrove river; or float the quiet Sangker through Battambang's rice paddies. Dinner cruises add live Khmer music and cuisine.
Guided sessions on the sundeck as the river wakes up.
Classical Khmer dance performed on board after dinner.
Learn to fold an amok and balance Khmer flavours.
Onboard lectures on the empire, the river and its people.
Paddle off the main boat into quiet riverside channels.
Bikes ashore at silversmith and weaving villages.
Walk through family workshops where silver bowls are still chosen as the king's diplomatic gifts, and watch krama silk woven thread-to-cloth on Koh Okhna Tey.
Tonlé Sap · Kampot · TataiPaddle silently through flooded forest at high water, glide Kampot's firefly channels, or trace the crystal-clear Tatai River deep in the Cardamoms.
Pre-dawn with local fishersHead out before sunrise to set and haul nets on the Tonlé Sap — the lake that provides most of a nation's protein — or cycle car-free Koh Trong island.
Chaktomuk · four riversSee the capital as it was built to be seen — Royal Palace gardens, the colonial quarter and the new Bassac waterfront of floating bars and restaurants.
River travel in Cambodia scales to every budget — here's roughly what each tier costs per person.
Trade the long overland journey for a slow, scenic river passage from Siem Reap through Phnom Penh and on to Ho Chi Minh City — aboard the Aqua Mekong, Viking or Scenic, with curated village excursions, sundeck meditation and Apsara nights along the way.
