This is part of the tour. We embarked at Chao Phraya River near the Grand Palace.
We went through Bangkok's canals which shows the culture, houses, small temples, animal creatures (komodo) and way of living of people living in Bangkok.
It is great experience and the long boat is very clean and shiny inside. Just be ready from some water splashes. If we were asked to feed bread to thousands of fish in one area. I guess these are is a feeding area because there are a lot of big fish. I am not sure if they cooked this for food.
Overall it's a great experience better than the Tourist boat in Chao Phraya River.
