The crystal clear ocean waters of Kauai create the perfect environment for snorkeling. The warm waters and thriving reef system make it a natural choice for snorkeling. One of the reasons the reef system is so spectacular is it has been developing for millions of years. It has become a habitat for hundreds of species of fish, some of which are found nowhere else in the world. Plus, snorkel gear is available for rent at just about every hotel or oceanside attraction so it’s easy to grab a mask, snorkel and some fins and swim around the waters to explore the underwater world of Kauai.
