We came across a vendor on the steps of Wat Arun and asked if it were possible to have a Thornburi canal tour on a long tail boat for around 30 mins. The lady was very helpful and we negotiated a 40 min trip that also included the gentleman taking us back to pier N12 to suit our needs. We thoroughly enjoyed our journey. We took many photos and every moment felt magical as we navigated through the Klongs. No trip to Bangkok is complete without such a trip!
