I'm visiting the tropics and I'd like to go snorkeling in coral reefs to see fish, but I've never done it before. What equipment do I need?
user
Snorkeling is very common among tourists. You can probably just show up at the beach and rent a snorkeling mask, snorkel, fins, and a life jacket for a very small fee.  I'd recommend you try snorkeling on calm, flat water as it's more relaxing.

Don't life jackets prevent people from going underwater? Why would I wear one while snorkeling underwater?
user
Right, I was just going to say that you might feel more comfortable wearing a life jacket until you get comfortable with the water.  I've found that even the most advanced snorkelers prefer to wear life jackets in the beginning.

A life jacket is an inflatable vest that helps you float on the water. It's not supposed to prevent you from going underwater.
