Whale Tours

It is believed Humpback whales come to Hawaii because of the warm waters, good water visibility, varied ocean depths and lack of natural predators. They usually start to arrive as early as December and a few may linger as late as May, before heading back to Alaska to feed for the summer months.  Hawaii is the only state in the U.S. where humpback whales mate, calve and nurse their young. They are one of the most dynamic and interesting whales to watch, often exhibiting Arial behaviors such as breaching, tail slapping, and spy hopping.

Come join us to catch these majestic Humpback whales off Oahu’s north shore coast.

Turtle Tours

Complete your Hawaiian vacation with an authentic trip to the North Shore of Oahu to see some of the most majestic creatures of the islands up close and personal.

Shark Tours

We’ll travel offshore three to four miles to our cage moored in the beautiful cobalt blue water. The visibility is so good (often 150 feet or more) that you can actually see the sharks come up from the deep. Our cage can hold up to 8 people comfortably which allows small families to experience their shark dive together.
