A UNESCO World Heritage Site, Ayutthaya's historic temples are scattered throughout this once magnificent city and along the encircling rivers. Several of the more central ruins Wat Phra Si Sanphet, Wat Mongkhon Bophit, Wat Na Phra Meru, Wat Thammikarat, Wat Ratburana and Wat Phra Mahathat can be visited on foot.

It is possible to add more temples and ruins to travel itineraries by touring the city on a rented bicycle. An ideal combination of modes of transportation for visitors interested in seeing everything would be to hire a bicycle for the central temples and charter a long-tail boat to take a tour of the outlying ruins along the river.

Ayutthaya Historical Park is situated opposite the Chao Sam Phraya National Museum. The main attraction in the historical park is Viharn Phramongkol Bophit which houses one of the largest bronze Buddha images in Thailand.
