Hawaiian Islands Humpback Whale National Marine Sanctuary is at 726 S. Kīhei Rd. Two-thirds of the North Pacific humpback whale population migrates from Alaska to Hawaiian waters from October through April to calve, nurse and breed. The sanctuary also is home to an array of marine animals, corals and plants, some of which are not found anywhere else on Earth. Facilities house hands-on exhibits and allow for lectures.
Adjacent to the sanctuary is Kalepolepo County Park as well as the ancient royal Kō‘ie‘ie Fish Pond, dating at least to the 1400s. Children can wade and swim in the pond.
