The jungles and rainforests of the world can be inhospitable places to visit with high humidity, hot temperatures and plentiful insect life. Yet they are also some of the most rewarding, with the greatest diversity of flora and fauna, some ancient peoples and many of the worlds greatest ruins. David Attenborough rates seeing mountain gorillas in the jungles of Rwanda as his greatest wildlife experience ever. On the other side of the world there is the Amazon jungle; it is simply vast and contains more biodiversity than the rest of the world put together. A trek through the jungle in Madagascar will reveal many indigenous species found nowhere else on the planet. So, they may be easy places to explore but with the help of a good Exodus guide, the wildlife you come across will make the effort well worthwhile.
