Express boat (public transport) for a budget, nice way to reach historical area of Bangkok (Grand Palace, Wat Po, etc..) very easy to get there by bus or a taxi

There is a water taxi that starts at this pier and takes you to the heart of the city. One of the nice things is that there are no traffic jams!
