The Hawaiian Islands Humpback Whale National Marine Sanctuary protects critical habitat for the endangered humpback whales and offers exceptional opportunities for marine wildlife viewing and water-based recreation in Hawaii’s waters.
Located in the waters surrounding the main Hawaiian Islands, the Hawaiian Islands Humpback Whale National Marine Sanctuary spans approximately 1,400 square miles of protected marine area. Established in 1992, this sanctuary safeguards essential habitat for the North Pacific humpback whale population, which migrates annually to these warm waters for breeding and calving. The sanctuary encompasses important coastal and offshore waters from Kauai to Hawaii Island. The marine ecosystem here includes coral reefs, seagrass beds, and diverse fish and marine mammal species. During the peak whale season from mid-December to May, visitors can observe the spectacular behaviors of humpback whales such as breaching, tail slapping, and singing. The sanctuary promotes responsible whale watching, boating safety, and marine conservation. In addition to whale watching, popular recreational activities include kayaking, snorkeling, scuba diving, and paddleboarding. Land-based vantage points along several islands offer accessible spots for whale observation without entering the water. The sanctuary works closely with local communities, researchers, and educators to foster stewardship and deepen public understanding of marine ecosystems. Its proximity to major Hawaiian towns makes it a highly appealing destination for visitors interested in wildlife, marine science, and Hawaiian culture.
