On this day we took the Majestic Circle Tour from Aulani. The tour was not bad, but did spend a bit too much time in gift shops (not shown in video) rather than exploring the natural beauty of the amazing island. The waterfall in this video was definitely the highlight of the day, and something that I would go out of my way for.
