In Ratchaburi you find this floating market. The floating markets were part of the traditional way of life of communities along the riverbanks of Siam. It's very special to experience this kind of market, but you have the same possibilities here as anywhere else.
If you feel hungry, just tell the driver of the boat to stop by one of the boats where food is prepared. Or you can just buy some of the fruit that lots of market salespeople offer you from their small boats. There are so many nice fruits for sale that it's hard to decide which to buy.
My favorite is mangosteens, whose flesh looks and tastes a little like grapes, but the skin is thick, red, and has soft spikes, with a large stone in the middle.
