My husband and I recently stayed in Hoi An for 4 nights as part of a holiday in Vietnam. We contacted Philong Tours to set up a private tour of My Son temple ruins and Marble Mountain, both outside Hoi An. We were set up with a driver and Mr Thanh was our excellent guide. They picked us up at our hotel at 5am, so we could get to My Son just after sunrise and pretty much have the place to ourselves, as we photographed the beautiful ruins in the morning light. Mr Thanh speaks English very well and is a wealth of knowledge about the history and the culture of the area, and Vietnam in general. He told us all about the Hindu community who built the temples at My Son and about it's rediscovery by the French in the 19th century, etc., up to modern day. He also provided a great deal of history and information about the Buddist shrines built into the caves at Marble Mountain. Mr Thanh's commentary added greatly to our experience and we thoroughly enjoyed the entire tour. I highly recommend Philong Tours and Mr Thanh.
