About this site
Batu Mera lies along the Lembeh Strait off the northeastern tip of Sulawesi, Indonesia, a stretch of coast known for its black volcanic sand slopes facing Lembeh Island.

Batu Mera is rated a beginner site, making it an accessible option among the strait's better known muck-diving grounds.
