Achasan

Mount Achasan is 295.7 meters high and stretches from Seoul to Gori. It is a very popular hiking spot for locals and tourists alike. It takes about 40 minutes to climb to reach the summit, which offers a stunning panoramic view of the Han River, Seoul and the surrounding areas. Twenty forts were discovered along the mountain, and their origin was estimated to date back to the Three Kingdoms era. Research indicated that some of the ruins were actually part of a military fortification that was built during the Goguryeo era. In light of these findings, the mountain was officially designated as a historical site in 2004. .
