Pretty neat place to visit. We rented a motorbike from Hoi An and make the trip out. It was great to be on a bike and not on a bus. The ruins are impressive although we didn't have enough time to see them all. I would recommend the trip, even just to ride through the more rural parts of the countryside outside Hoi An.
