Go big or go home on one of the most ambitious tours Kauai has to offer—a 90-mile ocean adventure up the Napali Coast and across the Kaulakahi Channel to Lehua Crater and the “Forbidden Island” of Ni’ihau. We’ll experience Kauai’s sacred and breathtaking northwest coast and then head offshore into the deeper and more remote waters of Lehua and Ni’ihau where there are superior wildlife viewing opportunities and world-class snorkeling conditions. Snorkeling gear and instruction are provided, and our sleek and comfortable Kauai-built 65’ power catamaran is the vessel to take you and your loved ones there and back safely and in style. Breakfast, lunch, and beverages (alcoholic and non-alcoholic) are included in this beautiful, exciting, informative, and valuable 7-hour ocean experience that’s very likely to become the highlight of your visit to Kauai.

Recommended: Purchase one tour per car, not per person. Everyone listens together! Buckle up for a tropical adventure you’ll never forget! Cruise through lush jungles, walk along pristine beaches, and dive into the history of the beautiful island of Kauai. Learn about the culture and how everything changed when sugar plantations arrived. Hear about clashing cultures and… a failed Russian invasion? No, really!

Fastest crossing and closest harbor to Ni'ihau! Your crew will be Nick and Jessie. We are experienced captains and snorkel guides.Visibility is usually 100’s of feet, and you are likely to have close encounters with Hawaiian Monk Seals! Sharks, bait balls being hunted by predatory fish, manta rays, and walls of butterfly fish are common. We will also tour Lehua Crater, an extinct tuff cone volcano and now a seabird sanctuary that is home to at least 16 different species of seabirds. In between snorkel sessions we serve lunch and do a tour of Lehua Crater, pointing out all our favorite seabirds and showing off the beautiful “Keyhole”. We usually look for dolphins, whales (december-april) and manta rays as we do a mini tour around the Lehua crater.
