The chain of islands that make up the Florida Keys is known for its tropical atmosphere. If you're looking for warm, shallow turquoise-colored water with few waves and good snorkeling, you've definitely come to the right place.
The Keys extend over 200 km from the tip of Florida to Key West. They are coral islands protected by reefs. These reefs provide excellent snorkeling opportunities. Most beaches in the Keys are natural, however those in Key West tend to be man-made with imported sand.
