Wedged between Mokulele Highway and Sugar Beach, this 700-acre wetland reserve provides habitat for endangered Hawaiian stilts, coots, and ducks. The picturesque ponds work both as bird preserves and as sedimentation basins that protect coral reefs from runoff. Check out the new visitor center, then take a self-guided tour along a boardwalk dotted with interpretive signs. Among the native waterfowl seen here are the black-crowned high heron, Hawaiian coot, Hawaiian duck, and Hawaiian stilt. From July to December, the hawksbill turtle comes ashore to lay its eggs.
