Wailua Falls in Kauai is an 80 foot waterfall that was featured in the opening credits of TV's Fantasy Island for many years. Typically, Wailua Falls is a double waterfall, but depending on the water level of the stream, it can have three channels of water spilling over the drop. After big rain storms, when the water level of the stream is very high, the falls all merge into one large waterfall spanning the entire channel.
It's hard to describe the sheer majesty of Kauai's Napali Coast, with its sheer, razor-sharp ridges that seem to drop straight to the earth. By helicopter, you're privy to cascading waterfalls and hidden inlets, and depending on your pilot, you might even swoop down into a cave. If you thirst for the sea, catamaran cruises and zodiac tours are the way to go. For experienced hikers, the multi-day hike along the rugged coast is among Hawaii's most scenic.
