Four miles before Hana, off the Hana Highway, is this beach park, which takes its name from the legend of the Waianapanapa Cave. Chief Kaakea, a jealous and cruel man, suspected his wife, Popoalaea, of having an affair. Popoalaea left her husband and hid herself in a chamber of the Waianapanapa Cave. A few days later, when Kaakea was passing by the cave, the shadow of a servant gave away Popoalaea’s hiding place, and Kaakea killed her. During certain times of the year, the water in the tide pool turns red, commemorating Popoalaea’s death. (Scientists claim, less imaginatively, that the water turns red due to the presence of small red shrimp.)
Waianapanapa State Park’s 120 acres contain 12 cabins (p. 148), a caretaker’s residence, a beach park, picnic tables, barbecue grills, restrooms, showers, a parking lot, a shoreline hiking trail, and a black-sand beach (it’s actually small black pebbles). This is a 6 wonderful area for shoreline hikes (mosquitoes are plentiful, so bring insect repellent) and picnicking. Swimming is generally unsafe due to strong waves and rip currents. Waianapanapa is crowded on weekends; weekdays are generally a better bet.
Maui has beautiful beaches on South, West and East side.
