The mouth of Khlong Bangkok Noi is located beside Siriraj Piyamaharajkarun Hospital (SiPH) and the former Bangkok Noi railway station (now the location of Thonburi Railway Station Pier).
For this reason it has been promoted as one of the cultural tourism routes, as well as other canals in Bangkok and the vicinity.
[1] [2] The canal, along with its counterpart Khlong Bangkok Yai, was initially a meandering part of the Chao Praya River's original course.
In 1552, during the reign of King Chairachathirat of the Ayutthaya Kingdom, he ordered the construction of a canal bypassing the meander to shorten travel time, known as Khlong Lat Bangkok (คลองลัดบางกอก; 'Bangkok Short-Cut Canal').
This scenery was recounted in at least two poems by Sunthorn Phu (1786–1855), a poet of that era, who was born in Bangkok Noi.
