About this dive site

This dive site is renowned for its dramatic underwater topography, mirroring the famous 'Mouth of Hell' cliff chasm above. Divers can explore a series of impressive arches, swim-throughs, and caverns carved into the rock. The main attraction is the spectacular landscape rather than a high density of marine life.
