Express boat service in Khlong Saen Saeb

Khlong Saen Saeb (in Thai: คลองแสนแสบ, also known as Saen Saep) is a canal (Khlong) in central Thailand, connecting the Chao Phraya River to Prachin Buri and Chachoengsao. A portion of the canal is used for public transport by an express boat service in Bangkok. The canal is lined with concrete walkways on either side in many areas where people stroll despite the foul smells of the canal, and in other areas the heavily polluted water oozes into adjacent properties, especially after heavy rainstorms. The canal is connected to many other canals in a large network, though most of the other canals do not have a regular transport service.


Bridge "Saphan Chaloem La 56" at Phaya Thai Road over Khlong Saen Saep, built in 1908 by King Chulalongkorn.

The Saen Saep canal was built by the order of King Rama III during the conflict between Siam and Annam about Cambodia, to establish a water transport for soldiers and weapons to Cambodia. The construction started in 1837 and was finished three years after.[1] Klong Saen Saeb was once filled with and abundance of lotus, King Mongkut in his 4th reign (1851-1868) built Sra Pathum Palace (Lotus Pond Palace) in Siam District, the names of the palace and present Pathum Wan district come from it.[2]

The Saen Saep starts from Mahanak canal or Khlong Mahanak (Thai: คลองมหานาค) around Mahakan Fortress (Thai: ป้อมมหากาฬ) in Bangkok. In Chachoengsao it terminates into the Bang Pa Kong River.

Public transportation[edit]

An express boat service operates on the Saen Saeb, providing fast, inexpensive transportation in traffic-congested central Bangkok. The service has a checkered reputation, due to the polluted water in the khlong and the haphazard nature in which the service is operated.

The 18 km route is served by 100 boats of 40-50 seats, and operates 5:30am to 8:30pm daily. Prices are 8 to 18 baht, depending on distance travelled. The service carries about 60,000 passengers per day. It is run by a company called Family Transport.

The service runs between Pom Prap Sattru Phai and Bang Kapi districts in Bangkok. At Pratu Nam pier in Pathum Wan/Ratchathewi districts is an interchange between the northern line, which terminates at Golden Mount, and the southern line which terminates at NIDA, where passengers must change boats. Boats go past Watthana and Huai Khwang districts, running parallel to Petchaburi Road.
