Thursday, 5 January 2023 - Left the Big Island and sailed to Nawiliwili Harbor on the island of Kauai, took a scenic riverboat ride up the Wailua River to the Fern Grotto with lush tropical foliage, then drove to Princeville and Hanaiei Bay for lunch, saw surfers and scenic views, visited Kilauea Point National Wildlife Refuge including the historic Kilauea Lighthouse and seabird sanctuaries, watched birds like Red-footed Boobies and Laysan Albatross in flight, and finished the day with a luau at Kilohana Plantation featuring traditional food and dance.
