Bonghwangdae

Sprouting huge trees of vast girth, this is the largest extant Silla tomb – 22m high, with a 250m circumference. It's quite a picture at any time put particularly at sunset, if you get the right light and the sun going down behind the hillock. Make sure you don't climb the tomb (it's tempting) – or any of the other mounds – as penalties are severe (up to two years in prison).
