About this site
This dive site off Siau Island features dramatic volcanic topography with black sand slopes and boulders.

The site's steep drop-offs and vibrant coral gardens host critters like pygmy seahorses and nudibranchs. Visibility often exceeds 20 meters, with water temperatures around 28°C. Best suited for experienced divers due to challenging conditions.
