The Gran Banc Exterior (The Big Outside Bank)
Located at the top end of the Mozambique Channel, the Nosy Be
Archipelago is one of the best places to experience advanced diving
in Madagascar, with thrilling currents and plentiful pelagic
action. If you're a shark aficionado, sink your fins into The Gran
Banc Exterior, otherwise known as The Big Outside Bank. Reaching a
maximum depth of 20 metres, this open-water site features a large
drop-off and requires good buoyancy control and air consumption.
The diving here is a little trickier than Nosy Be's other sites,
but the rewards include grey and white tip reef sharks, and, if
you're lucky, hammerhead.
The Radama Archipelago comprises four islands on the edge of the
Mozambique Channel: Nosy Kalakajoro, Nosy Ovy, Nosy Antany Mora and
Nosy Valiha. When it comes to advanced diving in Madagascar, Nosy
Kalakajoro is home to one of the area's best-loved dives, Greg
Plunging from the reef plateau at 13 metres to the depths below,
Greg Wall is a great place for deep diving as below 30 metres, the
wall is festooned with vivid gorgonians. Peel your eyes away from
the reef and you might even spot a whale shark or manta passing by.
Insider tip: take a torch as there are also a few caves to explore
Another site in Nosy Be, the Mitsio Wreck was scuttled in 2007
and is now a haven for a plethora of marine fauna. The former
trawler rests at 30 metres and wreck lovers can look for morays,
scorpionfish, batfish, trunkfish, frogfish, nudibranchs and
crocodilefish hiding in the vessel's nooks and crannies. For many
it's a must-dive when in Nosy Be, and if you're suitably
experienced, is also a fantastic night dive.
