The Khlong Saen Saep Express Boat service operates on the Khlong Saen Saep in Bangkok, providing fast, inexpensive transportation through the city's traffic-congested commercial districts. 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-kilometre route is served by 100 boats of 40-50 seats, and operates 5:30am to 8:30pm daily on weekdays (7pm at the weekend). Prices are 8 to 20 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 western line, which terminates at Golden Mount, and the eastern line which terminates at NIDA, where passengers must change boats.
