Tagulandang Strait

The waters around Tagulandang lie in the island chain between northern Sulawesi and Mindanao. Tagulandang, Siau and the larger island of Sangihe form part of a volcanic arc, with channels separating their steep shores. The Celebes Sea lies to the west and the Maluku Sea to the east, giving the passages between these islands a place on routes across both seas.
