I think it is a must to have a tour guide to bring the archeological sites to life, and Ertunga did it brilliantly. For those interested in history he did such a thorough job of explaining the different civilisations and telling it all like a story you want to listen to. He has a wealth of information on the site and history more general which I found fascinating. I really am very glad we dis this tour with Ertunga and would recommend him to all my family and friends.
