Our condo there was in a really awesome location with tons of restaurants and bars within walking distance, and an awesome view.
The first morning, I found a beach chair behind the resort next door to watch the sunrise.
The view of this lighthouse was spectacular, but unfortunately the area is under construction and we couldn't go all the way to it.
We never found Puff the Magic Dragon, but Hanalei is stunning even without him.
There's a botanical gardens tour, which is expensive and runs kinda long, but why do that when you can play miniature golf in there to play through instead?
The highlight of the entire trip, by far, was our charter to the Napali Coast. It's a pretty good deal. For $150 or so, you go out on a boat and are served breakfast, lunch, and beverages, plus free beer, wine, and mai tais as you head back. We stopped for an hour to do some snorkeling on the way out to the coast, and saw tons of dolphins and even a couple of whales, one of which jumped all the way out of the water and flipped over.
The Napali Coast is stunning. You've probably seen it in lots of movies.
Glass Beach is next to the boat tour company's office, and is completely covered with old broken bottles that have been worn down to the size of gravel. There's also a cemetery next door.
Waimaea Canyon is their equivalent to the Grand Canyon, but I like it better because when you leave it, you're in Hawaii instead of Arizona.
We did another coffee farm tour. This one's neater than the one we did in Kona because they've created a nicer gift shop and have a walking path you can take a tour on, but also have the self-guided option.
Kauai is really great. We had amazing food and tons of fun, and there are wild chickens everywhere. I'd go back any time.
