About this site
Blackrock Hiri sits off Hiri Island, a small volcanic island lying just north of Ternate in the Maluku province of eastern Indonesia. The site takes its name from the dark volcanic rock formations that characterize this stretch of coastline, shaped by the region's ongoing volcanic activity. Boats reaching this site typically depart from Ternate, the larger island to the south known for its own volcano and history as a former sultanate and spice trade center.
