Yes, of course Vietnam has many things to do, I did a 11-Day Vietnam &
Cambodia tour few years back and the tour took me through Vietnam from south to north as well as to
Angkor Wat &
Phnom Penh in Cambodia. There are many things to see during Cambodia tour including Tonle Sap River, Kampot Som, Ta Prohm and Mondulkiri hill and elephant trekking. The speciality of the Tonle Sap river is, it's the only river in the world that flows in both directions. If you plan your Cambodia tour betwen June and October, then you'll get a chance to see this wonder. During this time, the Tonle Sap reverses its flow and runs in the opposite direction. I went in September and really I amazed about the river, and due to this my Cambodia tour was an unforgettable one.
