Kawainui Marsh, Kailua

Kawainui Marsh is the largest remaining wetland in Hawaii. It's an 830-acre picturesque home to four species of Hawaii's endangered and endemic water birds: the Hawaiian Stilt, Hawaiian Moorhen, Hawaiian Coot and Hawaiian Duck. A community of rare fishes and snails also live here. There is a two-mile long levee that runs alongside the marsh. This is a good place to spot birds, take in the views of Mount Olomana and the Ko'olau mountains and take a jog. There is no shade so it's best to go early morning or in the late afternoon. Enter from Kaha Park or Kailua Road. – Shiyana Thenabadu
