Sea World Submarine Tour

This is a genuine submarine, not a glass-bottom boat — passengers sit below the waterline in a pressurized cabin and descend to around 22 metres, well past what a snorkeler could ever see, with large viewing windows along both sides.

It's one of only a handful of true tourist submarines in Egypt, and the main draw for anyone travelling with non-swimmers, young kids, or a member of the group who can't dive for medical reasons but still wants to see the reef properly.

The whole excursion, including a short boat transfer out to the submarine's dive point, runs about 2 hours.
