Hawaii's Garden Island of Kauai is known as the least touristy island in the chain, partially because it's still just so undeveloped. The center of the island, where the wettest spot on the planet resides, is impassable by vehicles and there are no roads whatsoever. So how can you experience the entire island, including Mt. Wai'ale'ale's usually cloud-covered peak? By plane, of course!
I took a narrated, hour-long flight from Lihue with Wings Over Kauai all the way around the island and even though I'd been to Kauai 3 times before, I saw sites I never knew existed, including the pictured waterfalls in Wailua. An aerial view is also the only way aside from hiking or boating that you can experience the pristine and wild Na Pali Coast. Some say it's the best way because you can see the whole expanse of it at once, not just small bits up close. Well worth doing!
