Having spent several weeks in the last two years travelling in Galapagos,I have bought and seen numerous guide books.This book stands out,combining the "best of the rest" in terms of history/background/climate/geology of the islands with a comprehensive field guide.The photos are informative and of the highest quality,the writing concise yet sufficiently detailed,and the section on the plants and trees is unique amongst the books I have come across.The visitor site maps are easy to read,attractive to look at and extremely useful.If you buy/take along with you only one book,I would make it this one!
