Wall diving fans will enjoy Abu Ajeen, which has a dramatic drop-off and a full orchestra of marine life that can be enjoyed along two optional routes. Best suited to advanced divers, the descent from the northern end takes you to 30m along a sloped coral garden with candy-coloured soft and hard formations. Giant sea fans, gorgonia and fat red finger sponges all grow happily, while fish life is abundant with titan triggerfish and parrotfish, vividly coloured yellowstripe goatfish, and lionfish fanning out their spectacular (though highly venomous) dorsal spines.

Take your time examining the hub of life on the coral heads and over the plateau before making a slow ascent, keeping clear of the substantial cluster of net fire coral, and looking out for giant moral eels, who seem entirely unafraid at the sight of visitors. At 10m, there’s an especially large colony of anemone swaying back and forth in the surge, where the sight of multiple clownfish darting in and out will please photographers.

If you’re up for some adventure, venture out deeper and over the plateau for a sheer drop-off. Those who do take the plunge beyond 40m will be rewarded with spectacularly coloured coral – but they may have to share it. Looking out to the indigo blue at these depths, you might see a solitary yet inquisitive giant grouper or giant trevally known to frequent the site.
