Bangkok Chao Phraya River Boats
The Chao Phraya Express Boat service operates along the Chao Phraya River and, together with cross-river ferries, connects both banks of the river in Bangkok. The public boat service is very useful for commuting in the central part of the city as well as for sightseeing, with a number of Bangkok’s top attractions, such as the Grand Palace, Wat Arun, and others, situated by the river.
Here you will find the most important information about the most affordable Bangkok river boat route - the Chao Phraya Express Boat Orange Flag Line.
Orange Flag Boat Bangkok - Chao Phraya Express Boat
Orange Flag Boat Bangkok was the most frequent express boat service, running all the way from Nonthaburi Pier (N30) to Wat Rajsingkorn Pier (S3) and making a stop at most of the piers along the way.
The Orange Flag boat costs less and is a good alternative to the pricier tourist boat, even if recently it stopped operating between 09:10 and 15:20 on weekdays and no longer operates on weekends and public holidays.
Bangkok Orange Flag Boat Route
The Orange Flag Boat makes a stop at 30 piers along the Chao Phraya River in Bangkok, even if some of the piers are skipped during off-peak hours. The route spans from Nonthaburi Pier (N30) to Wat Rajsingkorn Pier (S3), which is located south of the Central Pier. Also known as Sathorn Pier, the Central Pier is the main hub of Bangkok riverboats, as it is conveniently connected with the BTS SkyTrain Saphan Taksin station and can be easily reached from different areas of Bangkok.
The Bangkok Orange Flag Boat route consists of the following Chao Phraya Express Boat piers (south to north):
S3 / Wat Rajsingkorn Pier (close to Ramada Plaza Bangkok Menam Riverside)
