Beware the tourist offices in Nakhon! There are two and although they are both branches of TAT, Thailand's National Tourist Organisation, they give out conflicting information! There is one office in the city park off Thanon Ratchadamnoen south of the centre and one in the city hall also on Th. Ratchadamnoen, but right in the centre of town. The city hall desk has a computer terminal for tourist use which lists all the things to do in and around Nakhon and the staff speak good English. The city park office has a fair selection of tourist literature for the whole of Thailand, but the standard of English spoken there is poor and be careful of the information given there, I found it to be unreliable!
