Tropical foliage; clear, blue water; warm breezes; friendly people, and yes - chickens. These are things that stand out in my mind when thinking of Kauai.
Drive around the island and just let it seep into your bones, heart, and soul. I'm sure you will be glad you did.
Ke'ee beach past Hanalei Bay is my favorite. It is literally the end of the road on the northshore of Kauai. Cross eleven one-lane bridges, maneuver twists and hairpin turns, but go!!
Catching a sunset here is like nothing you've ever seen before. It will take your breath away (if you have any breath left after the drive up)!
Poi'pu Bay and Spouting Horn are two locations that are on the "don't miss" list.
An hour or so spent at the Lighthouse will be a pleasant surprise for you as it was for us. Go ahead and take the turn off to the lighthouse, it's well worth it. A bird sanctuary and whale watching location, it is truly a wonderful experience and one of the least expensive things you can do on any of the Hawaiian islands.
The golf courses and Prince Hotel in Princeville are also areas to explore. Be sure to have dinner at the Prince Hotel one evening. They have a menu that is awesome, and wonderful waitstaff. This was the best fine dining we had on Kauai.
Quick Tips:
Don't miss Ke'e Beach at "the end of the road"; the Prince Hotel for dinner; Waimea Canyon; Na'paali Coast and golf, golf, golf.
