I recommend visiting - Siem Reap, Cambodia
Cambodia is rightly famous for the temples of Angkor Wat and they are certainly something that everyone should see in their lifetime. Everyone has their own favourite temple and mine has to be Ta Prohm. Shadowed by the Cambodian jungle that looms over it, its walls and towers are locked in a deadly embrace by the giant strangler figs that have crawled all over it since the decline of the Khmer Empire.
Visit this temple at dawn when the mists are just lifting and the crowds are still in bed and it is one of the most atmospheric experiences you are ever likely to have.
