The Tiger Mountain stretch of the Great Wall, about 20km northeast of Dandong, is an excellent location to get your wall fix, far from the madding crowds. Running up a steep embankment beside the Yalu River, this restored remnant of the Ming dynasty makes a perfect day trip combined with a speedboat ride along the North Korean border. The Wall ends at a small museum with a few weapons, vases and wartime dioramas (buy your ticket at the main entrance).
From here two routes loop back to the entrance. Buses to the Wall (¥6.50, 40 minutes) run about every hour from Dandong’s long-distance bus station. A taxi from town will cost ¥35 and you can usually flag a share taxi back for ¥10.
