This is a useful if flawed guide for backpackers and other budget travelers. This thick book (1,150 Pages) covers lodging, conditions, airports, regulations, and other vital information for 13 countries. The information is practical, useful, and substantial, and one can travel South America with this guide. But in trying to cover 13 countries the book is unavoidably limited on information for any one nation, city, or place, and the maps are at times less than adequate. There is also some out-of-date information (Argentina's Peso is NOT equal to one U.S. dollar) so travelers are advised to check other sources.
If you will be traveling to only a couple nations in South America you would be better advised to buy a travel guide for each country. However, if you will traverse through many countries in this fascinating continent, this book is still a valuable reference tool.
