Location: northshore of Kauai, 6 miles before Na Pali
Features: Valley, viewpoints on the way
On the way to the Na Pali Coast trail, the road will take you along the north shore of Kauai with fantastic views into Hanalai Valley and other valleys close by. That part of the island gets the perfect mixture of rain and sunshine, so everything looks very lush.
It's kind of hard though to find a parking space for your car after you have passed Hanalai, because the road gets pretty narrow and winds along the coastline.
Nevertheless, at some points there are small gravel roads going off from the mainroad, they should give you enough space for taking good pictures...
