Located at the southern end of the Agincourt Reef, just around the corner from the continental shelf drop off, Castle Rock is a large pinnacle rising from a steep sand cliff. Visibility here is extremely good and Castle rock provides for superb deep and shallow dives. Circumnavigating the pinnacle the divers are likely to see White-Tip Reef sharks resting on the sandy ocean floor.

Almost every dive, you are met by “Axle” a 1.2m Malabar Cod, he is very friendly and will interact with divers, following them for the majority of the dive, he may even swim up to you looking to be patted. Curious Triggerfish will also swim close to have a better look at the divers. During the dive an abundance of Blue Lined Yellow Snappers and Sergeant Major Damsel fish will escort the group. Graceful Blue Spotted Lagoon Rays can also be seen “flying” underwater or buried in the sand, only their eyes and tails revealed.

Christmas Tree Worms are to be found extended from the tubes they create within the ancient Boulder corals while Lionfish may be found lurking in the branching corals. Daisy the Flowery cod may also make an appearance.
The reef flat surrounding the pinnacle is perfect for snorkellers and for a shallow finish to a dive. Giant clams can be found in the shallower water along with many different fish including various Parrotfish, Wrasse, Damsel fish and Rays. Blue-Green Chromis can be seen darting back into the Stagorhorn coral gardens for protection as they are approached.
