Kauai by road, with pickup from the cruise pier or the airport.
The island has one road and it does not go all the way around, so a day tour here is a there-and-back run down one side or the other. The south and west side takes in Waimea Canyon and the Spouting Horn; the east side runs up to the Wailua River and Opaekaa Falls.
