Rock Monster Chimney

Rock Monster Chimney is a Cayman Brac north-wall dive featuring a dramatic coral chimney swim-through that descends from the reef plateau through the shelf and exits onto the main wall face. The dive begins on the reef top at roughly 12 to 15 metres and divers enter the chimney near 18 metres, descending through the vertical coral-walled passage to exit onto the wall around 24 to 27 metres. The chimney walls and surrounding wall face are coated in giant orange elephant-ear sponges, barrel sponges, deepwater sea fans, black coral bushes, sheet corals, rope sponges and yellow tube sponges. Beyond the chimney mouth, the wall plunges vertically beyond 1,800 metres into the deep Caribbean. North-wall exposure on Cayman Brac delivers strong pelagic encounters: Caribbean reef sharks patrolling the drop-off, eagle rays gliding the wall edge, hawksbill turtles, schools of horse-eye jacks, Bermuda chub, Creole wrasse, queen and French angelfish, midnight parrotfish, and Nassau grouper. Visibility commonly exceeds 30 metres in the dry season. Currents can run moderate along the north wall, rating the dive advanced.
