The mighty Wailua River produces many dramatic waterfalls, and Opaekaa (pronounced oh-pie-kah-ah) is one of the best. It plunges hundreds of feet to the pool below and can be easily viewed from a scenic overlook with ample parking. Opaekaa means "rolling shrimp," which refers to tasty native crustaceans that were once so abundant they could be seen tumbling in the falls. Do not attempt to hike down to the pool. Just before reaching the parking area for the waterfalls, turn left into a scenic pullout for great views of the Wailua River valley and its march to the sea.
