Khlong Khao San or the Canal of the Milled Rice flows on the border between Phai
Ling and Suan Phlu Sub-district. It links
Khlong Dusit with the Pa Sak River. At par with
Khlong Hantra, Khlong Kramang and Khlong Dusit, this canal was probably once a
stretch of the Pa Sak River. [1] This canal is also referred to as Khlong Ko Kaeo. [2]

The King of Hongsawadi, having spoken, marched his army down to Ayutthaya on
the following day, on Wednesday, the tenth day of the waning moon of the second
month, 911, a year of the cock, first of the decade. The army of the Uparat, the
vanguard, set up its stockade in Phaniat Township. The stockade of the King of
Præ, the left wing, was set up at Thung Wat Photharam Township to
Kò Kæo

Khlong Khao San houses only one active Buddhist monastery, Wat Ko Kaeo at its
mouth on the southern canal bank.

The canal forms two islands: a northern island, bordered by a stretch of the Pa Sak River,
Khlong Ban Bat and Khlong Dusit and a southern island, called "Ko Kaeo" or "Crystal
Island" formed by a stretch of the Pa Sak River and
Khlong Khanom Tan.

In the Ayutthayan era, a thriving floating market existed at its mouth (Pak Khlong Khao
San floating market). [3]

The canal probably ran into the Front city moat, as King Maha Thammaracha (r.1569-
1590)  let dug an extension of the canal of the moat in front of the capital from the
Nang Plum monastery down to the mouth of Khao San canal. (1) [4]

Khlong Khao San can be paddled by kayak. A description of the
Khao San kayak trip
can be found on this web site under the section "kayaking".


(1) The Front city moat became in 1584 a riverbed of the Lopburi River. (See the essay
