Kompong Chhnang is the principal fishing port for Phnom Penh, and throughout the year supplies of fresh fish are packed with ice and loaded daily onto a fleet of trucks to drip their way towards the city. The fishing families, primarily ethnic Vietnamese, live on the river in floating villages, their houses built on pontoons which bob on the waters of the Tonle Sap. The villages are served by floating markets and coffee shops, and though facilities can be basic (their water, for example, comes from the river itself), most homes have TV and many have small floating gardens, while pens between the pontoons house farmed fish.
If you want to get out on the river and around the floating villages, boats can be hired from the riverfront near the boat dock (around 20,000 riel per hour for a small boat). Taking to the water offers an interesting insight into the daily life of these unusual communities and is a more relaxing experience than visiting the commercialized floating villages on the Tonle Sap at Siem Reap.
