This walk gives you an introductory look at the historic area surrounding the mouth of Bangkok Noi, one of the Thai capital's most important waterways.

Starting at the Pinklao Bridge, we'll walk through the grounds of storied Thammasat University, home to one of Bangkok's darkest and most violent crackdowns, before crossing the Chao Phraya River on a noisy-yet-charming river ferry.

Get your snack on at the well-known Wang Lang market before walking through the grounds of Siriaj Hospital, where you can check out the (in)famous forensics museum, one of Bangkok's strangest attractions.

We'll then check out the Royal Barge Museum before walking through a neighborhood that has character and local charm in spades. We finish off with a visit to a beautiful but seldom-visited Ayutthaya-era temple.

The tour is ready whenever you are and the audio plays automatically at exactly the right time and place using your smartphone's GPS and the VoiceMap mobile app, which also works offline.
