Begin with a sweeping journey along Nā Pali’s lush valleys, sea caves, and waterfalls aboard the comfortable 65-foot Holoholo catamaran built right on Kauai. After breakfast on deck, cross the 17-mile Kaulakahi Channel toward Lehua Crater and the secluded “Forbidden Island” of Niihau for world-class snorkeling in waters with visibility beyond 70 feet. The tour includes all gear, continental breakfast, deli lunch, soft drinks—plus beer and wine post-snorkel. With remoteness, cultural narration, and unmatched marine encounters, this is an adrenaline-fueled, memory-making all-day ocean expedition.
