• Take a Helicopter Tour of the Island: Don't leave Kauai without seeing it from a helicopter. It's expensive but worth the splurge. You can take home memories of the thrilling ride up and over the Kalalau Valley on Kauai's wild North Shore and into the 5,200-foot vertical temple of Mount Waialeale, the most sacred place on the island and the wettest spot on Earth. (In some cases, you can even take home a video of your ride.)
  • Explore the Na Pali Coast by Water: Unless you're willing to make an arduous 22-mile hike, there are only two ways to see Na Pali: by helicopter or by boat. Picture yourself cruising the rugged Na Pali coastline in a 42-foot ketch-rigged yacht under full sail, watching the sunset as you enjoy a tropical cocktail, or speeding through the aquamarine water in a 40-foot trimaran as porpoises play off the bow.
  • Duck Underwater: You haven't really seen Hawaii until you have seen the magical world underwater. Beneath those blue waves is an entire universe in itself. You'll see schools of rainbow-colored fish, dazzling corals, graceful manta rays, lumbering turtles, and quick-moving silvery game fish. If you are really lucky, you may see playful dolphins or the frequent winter visitors to Hawaii, humpback whales.
  • Hike until You Drop: Kauai is made for hiking, from the numerous trails in Waimea Canyon to the high forests of Kokee to the interior trails that give the island its special beauty.
