If snorkelling is said to be that much fun, then diving has to be twice as much! If you are a PADI certified diver then, you've just got to request a diving excursion at the front desk of your resort. Head out to sea and once you've entered the waters, you are in for a real treat with whale sharks, mantas and even dolphins. If you are not a pro in diving, there is no need to fret. The Maldives is full of diving schools you can sign up with for a 4-day course for your initial certification. A few hotels by chains like Anantara Hotels, Resorts & Spa might offer facilities for this as well.
