Kauai is a popular destination for nature lovers and outdoors enthusiasts. From the moment you fly over the island, you’ll see why Kauai is called the Garden Isle. As the greenest of all the Hawaiian islands, it’s popular with visitors who are into hiking, backpacking, and exploring as opposed to people who just want to chill at a beach resort.

While it’s possible to travel Kauai on a budget, costs can add up quickly, so be sure to check out this list of things to do in Kauai for free. Who knows, you might even be able to splurge on a once in a lifetime helicopter flight over the Kauai, or a sunset dinner sailing cruise around the island!
