The largest island in the archipelago, Unguja - more commonly
known as Zanzibar Island - is a magnet for big fish with epic
advanced diving. In Tanzania, there is a good chance of seeing
whale sharks and manta rays, especially between December and April,
which is also the perfect time of year to explore one of our
favourite offshore sites, Leven Bank. Leven Bank is a sunken
pinnacle reaching 12 metres below the surface, with strong currents
that attract hungry barracuda, kingfish, tuna, and trevally.
Zanzibar Island also enjoys a prime position along the migration
route of sperm and humpback whales, so keep your eyes peeled during
To the north of Zanzibar, Pemba Island has some of the best
advanced diving in Tanzania in the Pemba Channel. The channel's
nutrient rich water - a product of the north-flowing East African
current - attracts all manner of predatory pelagics; from marlins,
tiger sharks and hammerheads, to yellowfin tunas, wahoos, giant
trevallies and barracudas. Among the more advanced sites, Mtangani
and Mapanduzi offer good chances of hammerhead sightings, while
North Horn attracts white-tipped reef sharks, silvertips and
With over 50 species of coral and 460 species of fish,
Tanzania's first marine reserve, Mafia Island Marine Park, is one
of the most biodiverse marine regions in Tanzania. Muck and macro
enthusiasts have plenty of weird and wonderful creatures to find in
the shallows of Chloe Bay - part of the marine park - while those
looking for more advanced diving in Tanzania can venture outside
the bay and into the currents.
Kinasi Pass, the route into and out of Chloe Bay, is also a
great advanced drift dive featuring a pinnacle that resembles a
chicken. This is also a good place to spot pelagic hunters and
giant reef rays.
Once outside the bay, the dives involve fast-paced drifts.
Dindini Northern Wall is one of the best dives outside the bay,
with chances of seeing reef sharks, green turtles, large tuna and,
if lady luck is smiling, pods of friendly dolphins.
Not every dive in Mafia is classified as being among the more
advanced diving in Tanzania, but with healthy reefs and fantastic
marine diversity, the shallow sites are just as worthy of a few
dives as the more challenging ones. Visit between November and
April, and you're also virtually guaranteed to see whale sharks
