With all that's out there to be explored, it's no wonder that the Caribbean is home to many of the world's most popular snorkeling and scuba diving destinations. Before you dive in, take a few minutes to learn about scuba diving and snorkeling in these amazing waters.

The most important thing for you to remember is that, although often written and talked about together, snorkeling and diving are two very different activities. Snorkelers and divers can actually visit and enjoy many of the same spots, but certain locations are not suitable for both snorkeling and diving.

To get started snorkeling, grab a friend and ask your resort--most will lend or rent snorkels and fins to their guests. On many islands in the Caribbean, merchants on public beaches can rent out equipment as well, so even if you're not staying in a resort, getting ready to snorkel can be easy. Wear sunblock and a LycraŽ dive skin or long-sleeved shirt for the best protection; you'll be near the surface of the water and the sun will be overhead! Many vacationers don't realize they can get severe sunburn because the water has a cooling effect, but it also magnifies the intensity of the sun's rays.
