Castaway Island Resort popular dives sites.
 

Collies Pinnacles: (Intermediate Dive) Descend down mooring line and weave amongst pinnacles at 20 m, Beware that in lower visibility the last pinnacle is difficult to see from the fourth pinnacle unless you swim off into mid water. Take your time, as there is only a small area to cover, but plenty to see. This dive site is definitely best known for its amazing array of Gorgonian fans, which litter the pinnacles everywhere. Also the pinnacles are teaming with tropical fish life of all kinds, and many species of coral.
 
     
Magic Island: (Intermediate Dive) Located on the outer barrier reef, on the inside of a passage way with quite strong current in this passage. You will return in shallows with bommies heading back to the mooring line. You will find large variety and density of reef fish everywhere. Many resident Lion fish in & amongst the bommies, and watch for the very territorial big Titan Trigger fish. Also look for sleeping nurse sharks in sandy areas off the bottom of the wall, and cruising grey reef sharks.
 
     
Gotham City: (Advanced dive)
This must be dived at slack water due to strong current. Navigate around the two Coral Heads avoiding the current by hiding behind the pinnacles. Batfish and Moray eels await your arrival near the mooring line and very eager to be fed. Look out for Turtles, Maori Wrasse and Rock Cods. You will see an abundance of fish life everywhere. And don’t forget the soft corals in and amongst the bommies and hanging from the walls.
