Book excerpt: Remarkably Georgia, no larger than Switzerland, ranks in the world's top twelve for geographical diversity. It contains the heart of the Caucasus mountains--larger and more dramatic than the Alps--subtropical wetlands, a Black Sea coast, semi-desert, all peppered with ancient stone towers and an exceptional history. Peter Nasmyth has now provided the first comprehensive walker's guide to Europe's most diverse landscape, including birds, flora and fauna. The book contains clear directions, excellent maps, GPS references, local history, contacts and a superb selection of color photographs. Mta Publications, Exclusive distribution by I.B.Tauris & Co.
