Raro Fishing Charters offers seasonal whale-watching tours out of Rarotonga, running annually during the humpback whale migration season from July through October. Led by experienced local guides, these open-ocean cruises take guests past the reef to observe humpback whales in their natural habitat as they travel to the warm waters of the Pacific to mate and give birth. Passengers have the chance to witness spectacular surface behaviors, including tail-slaps, breaches, and views of mother-and-calf pairs, providing an immersive, memorable experience for visitors of all ages.
