If you’re planning to bring along your iPod, Zune or other MP3 player in your next trip to Italy, here is a good way to maximize the use of your device. WhiteHot Productions has released a series of personal audio tour guides of some key Italian destinations called Great Discoveries.
I had an opportunity to review their product and enjoy the professionally produced recordings with historically appropriate background music. You can preview some of the audio tour clips directly on their site. For several destinations, such as Palazzo Ducal in Venice, you can download and print floor plans and maps in PDF format as well.
Priced around $16 per audio guide, you may already enjoy some savings if you’ve two or more family members planning to rent the official audio devices offered by the museums.
Being a podcaster myself, I love the idea and I appreciate the quality implementation of these audio guides.

I think that these audio tours are really amazing. Such a great way to get more out of a trip without the shackles of booking a tour or carrying a great big guide book.
I found a site called tourdio to be really useful. It is an audio tour directory where you can find hundreds, if not thousands, of audio tours and podcasts for your mp3 player or iPod.
There is also a great site that brings all the audio tours and audio walks on the web together at http://www.audioguide2go.com
This site includes off the beaten track walks as well as top city tours and many of them are free. You just download and go.
Dont forget to add a review to help other travelers.
