Auditions for what exactly?
I myself am highly involved in community theatre and most every town boasts several of those that quite often have open call auditions for various shows.
If you want film or television that is a much harder process that takes a lot of time, determination, and luck. Sadly, in that business it is more about who you know than what you know and how you look than how you act. However, if that's your true dream than wading through the molasses of a process that it takes to finally make it big should be quite enjoyable.
Try searching on the internet for either of these perhaps search under "open call auditions" and the name of your city or the nearest big town to find local auditions. If it's not acting you're interested, try searching the same thing only being more specific as to singing, dancing, or whatever it is you wish to audition for. Newspapers nearly always have information about auditions for agencies or in the very least advertisements for coming shows at local theatres that have not yet been cast. Keep your eyes and ears open and I've no doubt you'll find a wide variety of auditions to choose from.
I hope this was of help to you.
Oh, and wish me luck because I have an audition tomorrow morning at a local theatre for James and the Giant Peach.
