Not sure I would pay to island hop *just* for this, but we enoyed the Jurassic Falls Helicopter tour on Kauai. There are photos in my trip report. It was about 90 minutes long and flew all along and in and out of the Na Pali Coast, over Waimea Canyon, and this was the only tour that actually stops at the waterfalls featured in Jurassic Park. The land is privately own and this particular company pays to be able to land there and have people walk up to the falls. We spent about 20 minutes there. This tour was pretty expensive, but we did see quite a bit. It was through Island Helicopters. While on Kauai, we also did Captain Andy's Sunset Dinner Cruise along the Na Pali coast which was awesome. We saw dolphins, and had an amazing dinner.
Of the three tours we did on Oahu, Kualoa Ranch was our favorite.
