Kawai Nui Marsh Trail

Kawainui Marsh is the largest remaining wetland in Hawaii, covering around 830 acres of land. It is a significant place for its historical, biological, and cultural importance, and has been recognized as a Ramsar Wetland of International Importance. The marsh provides habitat for several endangered Hawaiian waterbirds, including the ae'o, 'alae 'ula, and 'alae ke'oke'o. Visitors can view the marsh from multiple areas, including a walking trail that extends from Kaha Park, the Ulupō Heiau State Historic Site, and the Nā Pōhaku o Huawahine trail on Kapa'a Quarry Road. The trail is approximately 4.5 km long and is considered an easy route, making it suitable for families with children. The area is also great for birding, with many native species to spot, including the Hawaiian duck, northern shoveler, and Hawaiian gallinule
