We live in Ho Chi Minh City and sometimes go to Phnom Penh. We found out about this tour because the company Les Rives also operates similar day tours in Ho Chi Minh City (to the Cu Chi Tunnels, the Mekong Delta, the National Park, etc). We had tried them in Ho Chi Minh City and recommended them to visitors and friends as we had found them to be very unique.
We were really pleased to realize we could find similar tours in Phnom Penh (as there is not much to do there), and had a great experience once again with the 1-day river boat tour on the Bassac river. Of course the standard of the tour is the same as the ones in Ho Chi Minh City, which means the boat is top quality, the visits are very interesting and different from what you can read in guide books, the guides are friendly, knowledgeable and very attentive and the food is good!
We definitely recommend this tour for a unique 1-day experience outside Phnom Penh on the river and into the Cambodian countryside and are looking forward to trying new tours maybe in the future?
