Zanzibar
is starting to become a holiday destination for divers from
all over the world, divers who've already been, or don't
want to go, to all the famous dive spots, attracted to Zanzibar
and Pemba especially, for their untouched reefs.
Also
called Unguja, the south island of the Zanzibar Archipelago
has a reef going all along its eastern coast, offering many
diving possibilities. In the north-west, there are a few
dive spots in the middle of the ocean, rich with reef fish
as well as game fish.

Mnemba
atoll
This coral atoll in the north-east of Zanzibar, is a special
dive spot, famous for its visibility and turtles, as well
as for the dolphins that are often to be seen in between
the dives, and with whom everyone likes to snorkel. In October-November
and January to March, whale sharks are seen cruising close
to the reef. Stonetown also has a few dive sites to offer,
particularly two wrecks (30 and 40 meters).
Unlike
Unguja, this is not a coral island, but a rocky one, which
means that there are drop-offs all around the island, going
down to 200 meters or more. The coral is beautifully varied
and untouched, with amazing architecture, caves and tunnels,
strong tidal currents at times, and always a lot of fish
and some unexpected encounters like game fish (king fish,
barracudas, wahoos, trevallies, mantas, big rays)! Visibility
here can go to 50 meters.
Night
diving is a must in Pemba, as this is when you will see
the wildest creatures!
Mafia
This
island is still totally unknown, although it had Tanzania's
first marine park ( the southern half of the island ), supervised
by WWF. The diving there will be of discovery, but always
amongst big shoals of game fish and beautiful reefs.
