Abstract
The Togean Islands National Park is located at the Gulf of Tomini, Central Sulawesi Province, Indonesia. The islands officially become National Park in 2007, initiated by the government of the Tojo Una-Una district in 2004. There is a variety of geodiversity within the Togean Islands National Park, such as active volcano, ophiolitic pillow lava, beautiful beaches and islands formed by lithology of volcanic deposits, igneous intrusions and quaternary limestone formation. Four geodiversity areas are provided within the national park, according to lithological and geomorphological aspects. Those are the Una-Una Island active volcano, karst topography of limestone around the Batudaka Island, the lava dome at the Togean Island and the ophiolite complex of Walea Islands. The Una-Una volcano island is unique based on the location and anomaly in magma affinities. The Soliter volcano separated from the volcanic belt along the North Sulawesi Arm and has the adakite signature compared to tholeiitic - calk-alkaline as dominant affinities from the North Sulawesi island arc province. The Batudaka Island - karst topography offers sailing and cruiser to the beautiful shape and scenery of karst topography of limestone formation, cave, sandy beaches and blue ocean. The lava dome of the Togean Island: provides a geomorphological landscape that represents the dome of trachytic igneous rock above sea level. The Walea ophiolite: of a geoheritage showing rock formation, consists of ophiolitic pillow lava and the tectonic fossil of subduction between tectonic plates around Sulawesi Islands. Overall, the Togean Islands National Park proposes many adventure sites for diving, snorkelling, surfing, fishing, sea birds and dolphin watching and also conservation of reef, fish and geoheritage sites. Several facilities are already available inside of the National Park, such as resorts and cottages for accommodation, sailing and diving rental for leisure activities.
