Royal Dalton
Look up at the old plate corals from 22 m down the wall

A wall dive named for its old plate corals, worked by slipping down the face to 22 m and looking back up at the coral overhead. Some of the large plates have died and new growth is coming in over them, which makes this as much a site for watching a reef rebuild itself as one for the depth or the fish.
Where it is and how deep

The dive
Drop in on the wall and slip down the face to 22 m, then turn and look up into the corals above you. That is the whole trick of this site: the large plate corals are what it is dived for, and from 22 m down the wall they sit between you and the surface rather than being looked down on from the reef top. There is no route to follow here beyond the face itself.
The plates here are old, and some of them are no longer alive. Work along the wall looking for the new growth coming in over the dead colonies, which is the more interesting half of the site once you know to look for it. As bottom time runs out, get in close for the last of it, then leave the wall and drift back to the boat mid-water rather than following the reef home.
