 Join Hawaii Audubon Society for a walk through Kawainui Marsh.

Wear walking shoes and bring water, sunscreen, and hat. Walk will finish by noon.

We will walk the 3 mile, round trip, paved levee. No elevation gain and no cover from the sun. Kawainui Marsh State Wildlife Sanctuary in Kailua is 830 acres, the largest remaining freshwater wetland in the state of Hawaiʻi. The Kawainui and Hāmākua Marsh Complex has been designated as a Ramsar Convention Wetland of International Importance especially for the conservation and sustainable use of wetlands for waterfowl habitat.

The Kawainui levee is a 6,300 foot earthen berm and concrete wall that runs along Kawainui Stream. The levee was constructed in 1966 by the Army Corps of Engineers to protect the Coconut Grove neighborhood of Kailua from flooding.

The trail through the marsh offers beautiful views of the Ko’olau Mountains. This protected area is a haven for native birds and wildlife, such as the federally endangered waterbirds Hawaiian Stilt (aeʻo), Hawaiian Gallinule (ʻalae ʻula), and Hawaiian Coot (ʻalae keʻokeʻo).
