Kauai is a very pretty island and I'd advise that all visitors should try and see it from the air. I was surprised at how inexpensive an hour’s flight round the island was, and got more photos from this flight than the all of the rest of the trip combined. The flight flies a loop out to the steep sea cliffs at the far side of the island before passing between the mountains (taking in a view of the highest / wettest point) and flying over the more lowland areas to finish off with an arial view of a waterfall into a cenote like feature. The tour firm pick you up from and drop you back at your hotel and ensure that you get at least one photo of yourself standing in front of the plane. The only slight issues were that towards the end of the flight the turbulence was becoming stomach churning to the point where I couldn't have taken much more, and the flight was about 5 minutes short of the hour. Other than that the cloud base was high enough for us to see everything and I'd strongly recommend this tour as you’ll see swathes of the island that you simply can’t see by any other means.
