A picturesque view of Makalawena Beach on the Big Island of Hawaii. The wetland area behind Makalawena beach (the shore of Puu Alii Bay) is listed as a National Natural Landmark. It is known as Opaeula Pond (Hawaiian for "red shrimp"), and was the site of an old fishing village of 7 or 8 houses, wiped out in the 1946 tsunami. Its 12 acres (4.9 ha) provide one of the last remaining nesting grounds of the aeo (Hawaiian Stilt, Himantopus mexicanus knudseni), the alae keokeo (Hawaiian Coot, Fulica alai), and the only known breeding area for the aukuu (Black-crowned Night Heron, Nycticorax nycticorax hoactli) in Hawaii. It is located at coordinates 19°4732N 156°131WCoordinates: 19°4732N 156°131W, in the privately-owned area between the two sections of the state park...The park is open 9:00 am 7:00 pm daily except Wednesdays. A paved road 2.6 mi (4.2 km) North of Kona International Airport leads to Maniniowali (Kua Bay), and an unpaved lava road leads to Mahaiula. The Mahaiula section has a sandy beach and dune with a picnic area. A 4.5 mi (7.2 km) hike north on the historic coastal trail, Ala Kahakai, connects Mahaiula and Kua Bay. A hike to the summit of Puu Kuili, a 342 ft-high (104 m) cinder cone, offers an excellent view of the coastline.
