Shanhaiguan (literally the pass between the mountains and the sea), is a town at the northern tip of the Bohai Gulf. Originally built as a fortress in the Ming Dynasty, the town was an outpost to defend the eastern end of the Great Wall. This section of the wall still runs through the eastern part of the town, before winding south to the sea. The Eastern Gate (Zhengyuan Lou), a double storey, double roofed tower built in the Ming Dynasty (1368-1644 AD) attracts the most tourist attention.

The Great Wall Museum (Changchang Bowuguan, RMB15; open 6:30-18:30 in summer, 8:00-17:00 in winter) is next to the gate. It exhibits some interesting pictures, relics and clothes, depicting the life of this section of the wall. From the top of the wall you can see the crumbling wall as it zigzags on the mountain ridges northwards and as it winds south before plunging into the sea.

The town is small enough to walk around, peaceful and pretty. And the surrounding countryside contains some sturdy fortifications and remnants of the wall. The best thing to do here is to rent a bike and spend a few days exploring.
