By Tuk-Tuk
Alternatively, you can get around town by tuk-tuk motorized 3-wheeler. Ayutthaya's tuk-tuks are larger than the Bangkok variety and you can easily squeeze six people in on facing benches. Only "official" tuk-tuk drivers or tourist "helpers" can pick up passengers from the train station. You can verify their status by looking for their photos/name on a "Tourist Officials" board displayed at the southern end of the platform. These people are required to charge/work for fixed charges, usually quoting 300 baht/hour, but this can usually be bargained to a slightly lower price eg. 1000 baht for 4 hrs.
You can also flag down tuk-tuks from the street and try to hire them, most drivers carry with them a stack of postcards featuring the famous sites of the city to ease communication, they also are used to the standard temple hopping circuit. If you have a map you can point out any of the destinations that you wish to see and they'll often quote a trip price and will wait for you at each stop. 200 baht per hour seems to be the starting point for tourist tuk-tuks picking up backpackers away from the station, although it can be possible to negotiate a lower price.
By ship
Boat trips to enjoy the beautiful scenery and Thai lifestyle along the Chao Phraya River, the Pa Sak River and around the town island of Phra Nakhon Si Ayutthaya are available. A long-tailed boat can be chartered at the pier in front of Chanthara Kasem National Museum, Pom Phet Pier, and Wat Phananchoeng Pier. The fare depends on the route and duration. Rice barges are also available for groups that offer a relaxed way to see Ayutthaya.
