Just 6km from Can Tho in the direction of Soc Trang is Cai Rang, the biggest floating market in the Mekong Delta. There is a bridge here that serves as a great vantage point for photography. The market is best before 9am, although some vendors hang out until noon. It is quite an experience to see this in full swing, but it is well worth getting up extra early to beat the tour group crowds or you may end up seeing almost as many foreigners as market traders.
Cai Rang can be seen from the road, but getting here is far more interesting by boat. From the market area in Can Tho it takes about an hour by river, or you can drive to the Cau Dau Sau boat landing(by the Dau Sau Bridge) , from where it takes only about 10 minutes to reach the market.
