If you enjoy natural history, you'll find Darwin's account of his five-year journey around the globe in "The Voyage of the Beagle" both accessible and interesting. His trip is recounted in exhaustive detail -- which I found really enjoyable when he was writing about a subject I was interested in and somewhat tedious when he was talking about geology, which I don't much care for reading about. The most enjoyable part of the book was the account of Jemmy Button, York Minster and Fuegia Basket, natives of Tierra del Fuego who were brought to live in England and then brought back home, followed by accounts of South American animals and plants. (Having read "Uttermost Part of the Earth" previously, it was fun to see another account of their trip.) Overall, the book is a fascinating look at the early exploration that helped shape Darwin's theory of evolution.
