Yangdong is a village that was never really meant to be seen. The Wolseong Son clan and the Yeogang Yi clan settled in this fold of hills north of Gyeongju in the fifteenth and sixteenth centuries, and over the next few hundred years the two families built the tiled mansions of the elite on the upper slopes and the thatched houses of everyone else below, all in careful relation to the hillside. It is one of the best preserved clan villages in Korea, and in 2010 it joined Hahoe, near Andong, on UNESCO's list of historic villages of Korea.
Walking through it, you notice how it works as a diagram of the old social order. Houses climb the ridges in four spurs shaped like the Chinese character for water, the main halls face the river with an eye to feng shui, and scholars' pavilions sit where the view is best. Dry stone walls, persimmon trees and kitchen gardens fill the lanes between. It is a living village, and residents still farm here, so keep your voice low and stay on the paths. Scholar-officials from these families served the Joseon court, and some of their descendants are still around.
On a motorbike, the area is a pleasant mix. The approach from Pohang or Gyeongju is on regular main roads with good surfaces and plenty of cameras, so watch your speed, and then the road narrows into the valley. The rolling country around Gyeongju is excellent for gentle riding, with rice terraces, ancient burial mounds and low pine ridges. Gyeongju was the capital of the Silla kingdom for nearly a thousand years, and the Tumuli Park belt just south, with its great grass-covered royal tombs, is worth an hour at least.
Fuel is easy at Yeonil and Pohang, and Pohang, a big steel city, is also known for its raw fish. Gyeongju itself serves a very good ssambap, with rice and grilled meat wrapped in lettuce. Spring cherry blossom is spectacular but crowded, and autumn is clear and dry, a better season for riding. Summer brings monsoon rains in July.
