The first thing we did in Kauai was take a helicopter tour around the island to get our bearings. It was a nice way to get an overview of what we planned to attack by car, and see what the Napali Coast looked like from above; the Kalalau Trail was at the top of our list of Things to Do in Kauai. We also saw Wailua Falls from up top, and after chasing waterfalls in Iceland, we wanted to check this out. It's kind of a sketchy hike down -- definitely recommend proper footwear (that I clearly wasn't prepared with) since the trail is steep and muddy. But we couldn't resist after seeing a few people swimming in the water. Even though it felt a little unsafe, it was definitely worth the adventure and a good dry run for the more serious hike we had planned the next day.
