A small coral island standing off the seabed with a vertical wall on one flank, dived to 19 m and run as an Open Water site. Scubaqua lists it as a macro-rich dive and names lobsters, schools of snapper and grunt, barracuda and hawksbill turtles among what works the island.
Where it is and how deep
17.4746° N, 62.9934° WPublished position for this site.
The dive
The feature is a small coral island standing off the bottom with a vertical wall on one flank. Nineteen metres is the maximum depth published for the site, so nothing here is out of reach on a single tank and the whole island can be worked at whatever pace suits you. That depth is also why it is run as an Open Water dive rather than a staged one.
Scubaqua runs it as a macro dive, so pace matters more than distance covered: lobsters and the small life on the coral are what the site is listed for rather than any one big feature. Schools of snapper and grunt, barracuda and hawksbill turtles are the larger animals named here, and at 19 m there is time to lap the island once and then go back over whichever stretch was working.
