When in Bangkok: If you drive on Rama 4 road coming from the Lumpini park side, turn right into Kasemrat road just before reaching Carrefour or Lotus. Follow Kasemrat road right down to the Port Authority, about 1.5 km. Around the corner from the Seven/11 there is a temple called "Wat Klong Toei Nok". At the end of the soi there is a gate which will lead to a small jetty where boats depart to Bangkrachao. The boat ride will take only 5 minutes. There are ferries every 15 minutes. The ferry boat is 5 baht, individual boats 10 baht per passenger.
