Hapdeokje Reservoir (합덕제)

Hapdeokje is a reservoir located in Dangjin, Chungcheongnam-do. Designated as a Chungcheongnam-do Monument in 1989, it is known to have been built in the late Unified Silla period for the irrigation of Yedang Plain (Sodeulgangmun Gate). It attracts many tourists in spring with cherry blossoms and canola flower blossoms and in summer with lotus flowers in full bloom. The Hapdeokje Ecotourism Experience Center (opened in 2021) and Hapdeok Folk Irrigation Museum are located nearby, so you can stop by when traveling in the area.
