Beaver Reef is one of the most popular dive sites off Mission Beach with coral gardens, bommies and sloping coral walls in depths to 22 metres. Off the southern side of the reef is a site called Shark Alley. Cruising the sloping coral wall at this site are a constant parade of pelagic fish and reef sharks. It is common to see several whitetip and blacktip reef sharks on a dive at Shark Alley. The most popular dive site off the northern side of Beaver Reef is Beaver Cay. Just off this small coral cay are wonderful coral gardens in depths from 12 metres to 22 metres. While the usual array of tropical reef fish can be seen, divers should also keep an eye out for turtles, stingrays and reef sharks.
