What is the number one thing to do in Kauai?

A helicopter tour over the Na Pali Coast is the number one thing to do in Kauai. No road reaches the 17-mile stretch of 4,000-foot sea cliffs, hidden valleys, and cascading waterfalls — helicopter is the only way to see it all. Jack Harter Helicopters (69–399) is Kauai's most respected operator, known for knowledgeable pilots and doors-off photography option. Blue Hawaiian runs the Airbus EC130 with larger windows and climate control. A 60-minute flight covers Na Pali, Waimea Canyon, the Wailua River, and interior waterfalls. For those who can't do a helicopter, a Na Pali Coast boat tour with Captain Andy's (29–295) captures the cliffs from sea level with snorkeling included. Book either experience as the first thing you schedule — both sell out quickly and early morning slots give the best weather conditions.
