North West of Bangkok, why not visit Tiger Temple, where fully grown Tigers run free in the temple grounds. The Tigers are bred and cared for by Buddhist monks, who walk with them around the temple. You can get right up close to the Tigers and have your phot taken whilst petting them. An experience you will never forget! (You will have to sign a release form, in case you get eaten by one, has not happened yet, I think!).
