Dongmag beach area contains diverse geological and geomorphological outcrops which can be used for geotourism purposes. They are as follows; headland with granodiorite with plenty of enclaves and sandy beach, which is fed from Manisan with well-developed sheeting joints composed of granite and granodiorite. Weathered material from the hillside feedsthe one and only sandy beach in Ganghwado Island. Weathered outcrop at the hillside behind beach exposes typical spherical weathering also. Bunori Dondae Fort which was built on top of sea cliff with granodiorite has plenty of history and cultural values commands an extraordinary view of tidal flats and coastal landforms.
