It is an observation deck in the park located at the southernmost of Oshima, the island on Shimanami Kaido, which is the closest to Shikoku. Its height is 307.8 meters and it is possible to see Seto Inland Sea from here. This spot is not widely known. Visiting here during sunset time is highly recommended. The sunset is so beautiful that as the sun goes down, you will forget the time. You can also see illuminated "Kurishima-kaikyo Ohashi", world’s third biggest suspension bridge and the night city view of Imabari.
