Let’s get this out of the way, right away. While there are numerous whale watching cruises and shark tours throughout Oahu, there is none better than Nani Kai Ocean Adventures. They may be new to the game but they came into it packing history. The business is owned and operated by none other Kala “Da Captain” Alexander. A renowned North Shore surfer and waterman, Kala and his crew have a respect for the ocean and its wondrous creatures unlike any other ocean tour operator on Oahu if not the Hawaiian Island chain. This is not some cash grab sightseeing tour. Instead, it’s a fully immersive and highly engaging experience, no matter which tour/cruise you book. They offer dedicated whale watching and shark tours, but you can also book a Sunrise Cruise, Mid-Day Cruise, and Sunset Cruise (2-hours each).
