We love Kauai and the beaches are beautiful but having said that, there are other things about Kauai that are even more outstanding. We loved hiking the Kalalau Trail. We went about two miles in from Ke'e Beach and it is just beautiful. We loved the bird sanctuary at the Kilauea Light House. Waimea Canyon, kayaking on the river, searching for heiues, a sunset cruise on the north shore, the tree tunnel in Poipu. Hawaii and Kauai are so much more than beaches.
I have this same picture! I really felt this spot was very powerful....you could feel how it was sacred to them.
Anyways, I haven't read the entire thread, but if no one's mentioned it, my vote is to watch the sunrise on Mt. Haleakala (Maui). It's the most beautiful thing I've seen in my life. If you decide to go though, be sure to take warm clothes - it tends to get very cold up there!!
