In my past travel experiences, I have found great help inside bulky, yet somewhat necessary, Lonely Planet Guide Books. Many times I have found copies floating around in various unexpected locations, with tatty covers, missing pages and pre-highlighted for extra guidance. I have also been known to leave copies of these books lying around to inspire the next weary traveller. They are however, sometimes a little bulky and heavy and therefore lacking the characteristics of a good travelling companion.
It was to my sheer joy that I have just found the environmentally lighter version. Lonely Planet now offer the PDF versions. You can also simply buy just single chapters too should you wish to merely travel a specific area.
So, I have now downloaded the pdf version of the book and can carry it with me on my iPhone or iPad, or any other device that supports pdf’s. Perfect!
