North Shore Shark Adventures

Departing from Haleiwa Small Boat Harbor, the 1.5-hour trip heads offshore to view sharks in their natural habitat from a spacious aluminum diving cage. With masks and snorkels provided, floating inside requires no swimming skills or prior training beyond holding onto the bars. The boat ride through open water also brings chances to spot dolphins, Hawaiian green sea turtles, and humpback whales between November and May. Operating since 2001, it is Hawaii's original shark cage tour.
