Thonburi is an ancient Thai capital that's nestled on the banks of the Chao Phraya River. Even though it was merged with Bangkok in the early 1970s, it has surprisingly secured its old charm, part of which is due to the man-made network of khlongs or canals in this region. For an authentic taste of how the people of the olden days went about their daily lives, you could hire a longtail speedboat or even a hang yao as only narrowboats can pass through these canals. You could look forward to witnessing ancient teak houses and modern townhomes standing side by side during your khlong tour along with a smattering of magnificent temples and a rare crumbling shack that has its roots in the past.
