About this site

Sarena Island sits near the Lembeh Strait off the northeastern tip of Sulawesi, Indonesia, an area better known for the muck diving sites along the mainland and Lembeh Island shores. The strait separates Lembeh Island from the Sulawesi mainland near the city of Bitung. The site here is a reef reaching a maximum depth of around 28 metres. Divers have reported strong currents, upward flowing currents, and wave action, so conditions can turn demanding depending on timing. Angelfish, damselfish, unicornfish, and manta rays have also been reported around the reef.
