Bangkok is an ancient city. It is massive, chaotic, and confusing. Touring the city will sap up your energy and will bring you blisters the size of your own toes. I found that using the Chao Phraya tourist boats make moving from one tourist spot to another easier than hailing taxis and arguing with the driver when he gets the location wrong. It is also inexpensive at THB180 for the whole day. Here is my guide to using the river cruise to see all that you must see in Bangkok.
