Achasan Mountain (alt. 287m) stretches from Seoul to Guri City and is an extremely popular hiking spot for residents of Seoul and Guri City and the surrounding area. Towards the top of the mountain (about 40 minutes into the climb) a panoramic view of the Han River and Seoul unfolds at the mountain base.
During the Joseon Dynasty, what are now Bonghwa and Yongmabong Peak and the Manguri Cemetery were considered part of Achasan Mountain. Twenty bastions were discovered along Achasan Mountain that were originally estimated to date back to the Three Kingdoms Era. Further research indicated that some of the remains were actually part of a military fortress built during the Goguryeo Era. In light of these findings, it was officially designated a Historic Site No. 455 (2004).
