About this site
Tanjung Kusu-Kusu is a point on the Lembeh Strait, the narrow channel between mainland Sulawesi and Lembeh Island in North Sulawesi, Indonesia. This stretch of coast around Bitung is known for its dark volcanic sand slopes, reached by short boat trips from the shore resorts that line the strait. The site reaches a maximum depth of around 20 metres, keeping it within easy range for divers exploring these muck diving slopes.
