Kauai beaches are some of the best in the state of Hawaii, and Kauai is the oldest of all the islands in the Hawaiian chain and the fourth largest in terms of land mass. There are a good number of beaches on the island that are accessible to visitors. The most popular Kauai beaches on this island offer breathtaking natural beauty, fine sand, and protected, calm waters that are great for swimming, snorkeling, and just taking it easy. As with many of the beaches in Hawaii that offer seclusion and true privacy, there are not always a lot of public facilities, and few public beaches have regular lifeguards on duty. The bigger beaches on the island are within close proximity of hotels, restaurants, bars, and surf shops.

The right side of the bay is where advanced surfers will find challenging waves offshore, while breaks closer toward the pier provide perfect training grounds for novices.
