In Samut Prakan, the only way we can cross to the other side of the Chao Phraya River is to take a river ferry from the market to Phra Samut Chedi. The journey is about 10 minutes and costs only 2 baht. (At present, 37 baht is $1). This service runs 24 hours a day. During peak times, you only have to wait about 5 minutes for the next boat. As you can see from the photograph, underneath the roof there are a number of floats in case the boat capsizes. The river can get pretty rough at times and you also have to watch out for the large container ships heading up-river to Bangkok.
