Famous across China (although a little overhyped if we're being honest), Old Dragon Head, 4km south of Shānhǎiguān, is where the Great Wall meets the sea. It's photogenic for sure, but bear in mind that what you see now was reconstructed in the late 1980s – the original wall crumbled away long ago. Bus 25 (¥2) goes here from Shānhǎiguān’s South Gate, and its terminus in the other direction is Shānhǎiguān Railway Station.

To walk along the beach and bag the famous wall-meets-sea photo, you can bypass the attraction to the north via a narrow traffic tunnel through the Wall itself, and then hop down on to the sand.
