About this site
Leven Bank is a sea mountain in open ocean off northern Zanzibar that slopes from 12 to 55 metres, and it is one of Zanzibar's best dive sites. Strong currents are common, so it is for experienced divers only.
Be ready to descend quickly into the blue to reach the reef at 30 metres. Below is a beautiful slope with schooling unicorn fish, snappers and bannerfish, plus big honeycomb moray eels, lobsters and marbled rays. Barracuda, wahoo, tuna and rainbow runners may pass in the blue, and with luck you see Napoleon wrasse and groupers. Ascending, you drift into the shallows among fusiliers and corals, and look for large nudibranchs.
Humpback whales are often seen from the boat in August and September. Only a few days a month have sea conditions and tides that suit a dive here.
