The site has been (generally) well preserved and you can get a really good sense of the ancient city that used to be here. Although it is easily accessible from Hoi An, it does feel like it's in the middle of the jungle and that adds an air of mystery to it. While most of the artefacts that could be moved, have been - there are still quite a few statues that are part of the building.
I had a guide for my visit and that was worth it. I learned a lot about the Champa people and the way they put this place together. There is some work going on to restore some of the temples. Others that were bombed are probably impossible to salvage.
I enjoyed this site and it was quite different to most of the other WHS's in Vietnam. While not nearly as impressive as Angkor or Ayutthaya, they all fit together into the history of this region.
