I mentioned earlier that one of the main ways to get around Bangkok is up and down the river. I happened to be staying on the west bank of the river, while most of the stuff to see and do is on the east side. As the Thais like to say, "is no problem." The hotels on the west side know that it'd be inconvenient for guests to keep hopping taxis only to sit in bridge traffic, so they provide regular ferries to the east bank.

I rode a boat like this many times. These guys go back and forth across the river, about 90 seconds between docks, for roughly 18 hours a day. That's a lot of trips. My hotel ran ferries both to the light rail station, where you could take elevated rail to downtown or beyond, and the public pier, where you could hop on another, faster boat to head up or down the river. About once an hour one of the boats would take a slightly longer trip up to one of the shopping malls. And no, Chatuchak isn't on the river.
