My Son Sanctuary is a Hindu temple complex of the Champa kingdom, about an hour by car from Hoi An. Visitors can see red-brick temple foundations over a thousand years old along with a museum displaying Champa artifacts. After the entrance museum and a bridge, an electric shuttle carries visitors to the ruins, and traditional performances are held four times a day. There is little shade, so daytime is hot, and reaching the inner ruins requires a lot of walking.
