The Kabakari group of islands in the Seto Inland Sea, floating in the Akitada area, is the Tobishima Kaido, which is connected by seven bridges. One of them, "Hiroshima Prefectural Prefectural People's Beach", is located on the island of Kamikakari, a stay-in marine resort facing the calm waters of Setouchi. In addition to the seaside astronomical observatory, which is rare in the whole country, the site is fully equipped with a wide variety of facilities, including accommodation and hot spring facilities, a swimming pool, a gymnasium, and a tennis court. The "Prefectural no Hama Beach" is one of the most beautiful swimming beaches in the prefecture, which was also selected as the "Bathing Beach Hundred" selected by the Ministry of the Environment in 2006. Sea kayaks and sap tours are also held at Kamagari B & G Marine Center in the park.
