If lying on the beach with a book sounds like a bore, why not spend your vacation face to face with a 2,700 pound shark? Check out Shark Alley off of Dyer Island in South Africa, a breeding ground for whales, dolphins and a plethora of sharks. Instructors assist you as you deep-sea dive—while safely inside a cage—with Great Whites. Remember: This is an activity to do with professionals only.
Don't miss: The whale-watching tours because you might not have any adrenaline left after your shark excursion.
