Tumbak Marine Park

Tumbak Marine Park is a coastal marine conservation area centered on Tumbak Village in Pusomaen District, Minahasa Tenggara Regency, North Sulawesi, Indonesia. Located on the eastern coast of the Minahasa Peninsula facing the Maluku Sea, it is noted for extensive coral reefs, seagrass beds, mangrove forests and small offshore islands. The park supports snorkeling and diving activities and is managed with involvement of the local fishing community for reef conservation and ecotourism.

Visitors can expect a low-lying coastal fishing village with direct access to shallow coral reefs, seagrass beds and mangrove channels. The setting includes small offshore islands such as Pulau Tumbak and Pulau Bohonga reachable by small boat. Activities are water-based, with snorkeling and diving over reef flats, boat trips between islands and mangrove areas, and views of traditional fishing boats and stilt houses along the shoreline.
