The Palni Hills, including Kodaikanal and the surrounding villages, are a very distinctive area. The climate of the area is as effective a barrier to species migration as the waters of the ocean are to an island. These hills are, therefore, known as an 'island in the sky.' This book describes the early history of Kodaikanal, along with a history of the heritage buildings in the village. It also takes the reader through the flora and fauna of the hills in great detail. It will be useful as a guide to tourists visiting the area.
