There is shark-diving further to the south, too.

Diverse Travel is offering a seven-night liveaboard trip to Sudan on the liveaboard Oceanos from £1495pp (two sharing a twin cabin).

This includes flights from London to Port Sudan and transfers, plus three dives a day on all but the first and last days (two dives on each).

The first 10 bookers receive free nitrox if qualified. Diverse says the price will save you up to £125. Book by 31 October.
