About this site
Rawa Island sits off the east coast of Johor, Malaysia, in the South China Sea near Mersing, part of a small group of islands popular for boat-based diving and snorkeling trips out of that town. The Bat Cave site takes its name from a rock formation or cavern feature along the island's coastline, and it reaches a maximum depth of around 50 metres, rated as a technical dive. Divers have also reported batfish around the site.
