One of the best times is going on an Ocean Sports adventures. During December to April, you can go on a whale watch, and they offer a ton of other activities all year. We’ve been on their sunset cruise and snorkel adventure. I’m not much of a swimmer, but I stayed in the water almost the entire time! It’s like being on another planet.
Ocean Sports is definitely one of the best snorkel, whale watch and ocean activity companies in Hawaii. Plus, they’re really nice people!
