Footprint Backpackers' Patagonia: Backpacker's Latin America

I haven't gone on the trip yet so I can't comment on the accuracy of the book. I can say that it has help immensely with the planning process as it provides websites for most of the reviewed hostels and transportation services. It is very informative and was recently updated so I am assuming that the information is good. I can only give it four stars due to the fact that I haven't gone on the trip yet. Also, the book is smaller in size compared to the LP guidebook so you could easily take it with you on your trip without it being a burden.
