• The quickest way is to take the BTS Skytrain to Victory Monument and then No. 166 air-conditioned bus from the west side of the monument. The bus trip to Pak Kret takes around 20 mins via Expressway and costs only 19 Baht. The 505 bus, from Pratu Nam to Pak Kret, takes much longer as does the number 32 Bus from Wat Pho (more than 1 hour.)
The Chao Phraya express boat runs from Sathorn Pier to Pak Kret pier, but only between 06.15 and 08.05 in the morning, and 1605 and 18.05 in the afternoon. For the rest of the day it only goes as far as Nonthaburi pier; to continue to Pak Kret you need to take a bus (No 32) or long-tail boat (price negotiable).
