Shark Observatory.

Named for the high limestone cliff above where divers once scanned the water for sharks, this site features a spectacular sheer wall dropping hundreds of metres into the blue. The reef face is covered in soft corals, gorgonians and glassfish-filled overhangs, and the deep water off the wall is patrolled by tuna, barracuda and seasonal sharks. It is one of the most dramatic wall dives of the Ras Mohammed peninsula.
