When I go to the Grand Palace I take a boat up river. It's the fastest, cheapest (Bt. 16) and easiest way to go. If I want to hit Ramkhamhaeng or The Mall at Bangkapi, I take the MRT to Petchburi station and then head for the nearby klong boat stop.

Finally the BMA has realised the potential for much more klong travel as a way of relieving some of the city's traffic jams. 9 major klongs are to be cleaned up to pave the way for new boat services. Klong Lat Phrao will be the first canal targeted and developed.
