This is the Cai Be Floating Market!?
Frankly speaking we were disappointed as there were only a few boats doing trading. We were told that there would be flowers during end of year and more boats in early morning, say 6am, before the sun gets really hot in the afternoon. Maybe joining a 2-day tour would be better by getting there early on the 2nd day. However I read that merchants had decreased dramatically ever since the completion of bridges so goods are increasingly delivered by land instead of boat. So forget about this Mekong Delta tour and join the other cheaper one if you only got a day.
Overall this tour brought us to many places to buy things and we think the other cheaper day tour would be sufficient. Don't go for the Mekong Delta River day tour because there is hardly any merchants by the time you get there. It is better to go for 2-day tour if you really want to see the floating market in action.
