Kauai is geologically the oldest of the main Hawaiian Islands. With an area of 562.3 square miles (1,456.4 km2), it is the fourth largest of these islands and the 21st largest island in the United States.
Seventy percent of the island is inaccessible by foot, but it's still a hiker's and sightseer's paradise. The sheer beauty of Kauai is unsurpassed and adventure and exploration are the keys to enjoying this island to its fullest.
Part of Kauai’s unique charm is the fact that the island has remained relatively undeveloped. Visitors benefit from this by enjoying views of Kauai’s pristine, untouched Napali Coast cliffs where waterfalls sprinkle into the ocean, its majestic Mount Waialeale and other scenic treasures such as Hanalei Bay and Haena, both bathed in hues of green and blue.
