Welcome to Rachaburi! It means City of the King, so named because it was the birthplace of King Rama the 1st: the founder of the Chakri Dynasty that still rules to this day.
The town itself is unremarkable, but there are a couple of interesting sites surrounding it. The first is the ruins of Khu Bua, talked about in a separate blip to the south. You’ll be crossing the Mae Klong river runs through Ratchaburi town, and a little downstream is the Damnoen Saduak floating markets – one of the more authentic and enjoyable floating markets in Thailand. You can also visit the Damnoen Saduak Tiger Zoo, where you can pat adult tigers and feed baby ones for the small price of their freedom and my respect for you.
