One of the most important things you will need during your time in the Maldives will be sunblock. This is for the simple reason that if you have opted to visit during the peak seasons, you are going to find yourself under sunny skies during your trip. The thing about the Maldives is also that the only shade is really inside your resort so when you are moving about during the day, putting on some sunscreen will go a long way.
Another thing to keep in mind is that the sunscreen you do bring along will need to be reef friendly. This means that when you get in the water, the sunscreen would not go on to cause damage to the stunning reefs that surround the islands in the Maldives.
