If you’re up for a more difficult challenge, ocean kayaking is a seasonal alternative to experience Kauai by sea. On the South Shore, try the Poipu to Port Allen course with a stop in Lawai Bay. When conditions are calm, kayaking along the 17-mile Napali Coast is unforgettable. "National Geographic" deemed kayaking the Napali Coast the second best adventure in the country. Because this can be a physically demanding activity and the seas can be unpredictable, hiring a guide for this once-in-a-lifetime experience is a must.
