Ayutthaya is an island at the confluence of three rivers: the Chao Phraya River, the Lopburi River, and the Pa Sak River. As the train station is on the east side of the island, most visitors will need to cross the river by ferry boat. Navigating your way around the island is not particularly hard: U Thong Rd is a ring road that circumscribes the island completely. Most temple ruins can be found northwest of the island, while accommodation and nightlife are clustered around the northeast. As non-Siamese people were not allowed to live inside the city walls, things foreign are found off the island. Cr.Wikitravel
