Tomb of Khai Dinh (10km) - dating from 1925, this is the best preserved of the lot and, while comparatively compact, quite grand at first sight. While it follows the classic formula of forecourts leading up to the tomb of the Emperor, complete with statues in attendance, architecture buffs will spot some European influences. The tomb itself is completely over the top with incredibly detailed and opulent mosaics of cavorting dragons. Try to get to this one early, as it is a favorite stop for Asian tour-bus groups. Also, you may want to leave the tourist path and head up the hill on the right side of the tomb, where a small temple stands. You will have a great view of the tomb and the valley it faces.
