About this site

Twin Rocks is a marine protected sanctuary reef in the Philippines that has been growing back on its own for almost two decades. A sunken barge that began as a simple hull has become a coral garden.

The site is seen at 14 to 16 m (46 to 52 ft) and suits scuba divers, freedivers and snorkellers. Bubble coral, basket coral and nudibranchs grow here, with plenty of coral reef fish, and two sea turtles live on the site, which draws others as well.
