Posting this a day late. Oh, well.
We took a tour called "Best of Kauai", which combined a guided van tour, a boat cruise up the Wailua river, and an aerial tour (except that, due to mechanical issue, the aerial tour is postponed until tomorrow.) And I took nearly 100 photos, so I'm going to be picking and choosing...
The Wailua river is one of seven rivers on Kauai, and is said to be the only "navigable" river in the state.
Kilauea Wildlife Refuge at Kilauea Lighhouse. This is a nene, the State bird of Hawaii.
(110 feet to the water where I was standing, plus another 100 or more feet across the bay.)
