Once the ancient capital of Thailand, today a small satellite of the Bangkok megapolis.
It has many interesting ruins, good value boat cruises, and delicious restaurants by the river. A great place to visit.
It also has badly maintained roads, speeding drunk drivers in pickups, a serious problem with meth (yaba) , and garbage clogging the canals.
translation of two Thais from Bangkok talking:
Person 1: I'm moving to Ayuthaya
Person 2: That upcountry ghost town? Why?
