Located 1km (2/3 mile) north of the 38th parallel, there is a small pavilion, the Hajodae (dating back to the Joseon Dynasty), overlooking the sea. It used to be encased in barbed wire, but the government has recently removed most of the barbed wire from the eastern coast of the country. At the 38th parallel, there is a boulder indicating it. This is where the division was drawn at the end of World War II, so all points north of here were administered by North Korea. When the cease-fire was signed after the Korean War, territory above this line was traded with almost an equal amount of land north of Seoul, below the 38th parallel.
On the left side of the beach is an unmanned lighthouse, which is open daily from 9am to 7pm. You can see some spectacular scenery from there. The most popular times to visit are when the waters are warmer in mid-July through August.
