Kauai has the most beautiful beaches in Hawaii, noted for their beauty, serenity but also temperamental nature and powerful ocean. The winter months bring big waves to the north shore which dramatically changes the character of beaches. Kauai’s reefs offer reasonably good snorkeling. In the winter months Poipu becomes the preferred snorkeling destination, while in the summer there are several north shore locations that are popular including Ke’e Beach and Tunnels beach. Lydgate park offers good year-round snorkeling for beginners. For surfing, Hanalei Bay, Kalapaki Bay, and Kiahuna beach are sure to please.
It's important to check the surf report before visiting the ocean in Hawaii, so that you know what to expect. Remeber, the waves predicted by the surf forecast can arrive at any time without warning, so stay away from the ocean if bigger surf is predicted.
