The text is based upon my many years of experience as a geography professor and world traveler. I have found this part of the world to have extraordinary qualities and I highly recommend it. Rather than overdoing the minute details, as many of the famous tour books tend to do, this book is concise and aimed at travelers who generally have only hours or at most a full day in port. It provides you with all you need to know to enjoy each of the ports. It also gives you valuable geographic, historic and political detail on Argentina, Uruguay, Falkland Islands and Chile.
