Simon Reeve circumnavigates the globe around the 22,835 mile long Tropic of Cancer, visiting 18 different countries, meeting amazing people, witnessing bizarre and beautiful sights, and encountering spectacular and endangered wildlife. Starting in Baja California - the long strip of Mexico that descends into the Pacific Ocean, Simon travels through Cuba, the Bahamas, Mauritania, the wastelands of Southern Libya, India, Bangladesh and Burma before finally reaching the some of the most beautiful (and also some of the dirtiest) beaches in the world. From gorgeous landscapes to deserts, small fishing villages to violent drug wars, Simon finds out what makes these places fascinatingly unique.
