There are several impressive Royal Tombs around Hue from the Nguyen dynasty (1802-1945). You can rent a motorbike in Hue to venture the 2-16km to see them as they are spread around the banks of the Perfume River.
Located just to the north of Daegu (roughly behind the Daegu International Airport), the Bullo Dong Tomb park contains over 200 traditional Korean tombs dating from 37 BC to 935 AD. The best time to visit the tombs is in springtime, when the tumuli are covered in lush carpets of flowers.
