We did the Khe Sanh - DMZ - Vinh Moc Tunnels Tour with Mr Vu in early May 2019.
Booking the tour was easy, we used the excellent website and after a brief email exchange we were good to go.
Mr Vu collected us from our hotel in Hue spot on time and after introductions we set off on the journey to Khe San. We were given Mr Vu's iPad to watch an informative documentary on the battle of Dien Bien Phu to set some background information that was going to be useful going forward.
As the tour progressed Mr Vu's information and insights together with period photos from his iPad were brilliant and bought the subject to life for us. As an aside, as we left the Khe Sanh base and were driving back through the valley, Neil Young's "Old Man" came onto the stereo in the car randomly - quite evocative.
After a street food nice lunch we moved onto the Freedom Bridge and finally the Vinh Moc Tunnels - again, the insight and history were both fascinating and informative allowing a picture of what life must have been like.
One last thing. Any driving in Vietnam can be an experience, varying from entertaining to worrying. Having spent a good few hours in the car with Mr Vu, he is an excellent driver and at no time did we feel the slightest concern. Overall I cannot recommend Mr Vu or Annam Tours highly enough; brilliant itinerary, a great tour leader, excellent knowledge and fantastic value.
