6. There is No Daylight Savings
This is not Kauai-specific, but it is still a fun fact about Hawaii in general. Hawaii does not participate in daylight savings.
Because the Hawaiian islands are all close to the equator, there is no point in having daylight savings anyway.
7. 111 Miles of Beach on Kauai
Another one of the cool Kauai facts is that it has 111 miles of beach surrounding the island. This means you can get to the beach from almost anywhere!
Over 50% of the island has a shoreline, making it more accessible to enjoy the beautiful beaches than any other Hawaiian island.
8. Kauai Grows More Taro Than Any Other Island
