Kauai

Kauaʻi (Hawaiian: [kɐwˈwɐʔi]), anglicized as Kauai (English: KOW-eye or kah-WAH-ee), is geologically the second-oldest of the main Hawaiian Islands (after Niʻihau). With an area of 562.3 square miles (1,456.4 km2), it is the fourth-largest of the islands and the 21st-largest island in the United States. Nicknamed the Garden Isle, Kauaʻi lies 73 miles (117 km) across the Kauaʻi Channel, northwest of Oʻahu. It is the site of Waimea Canyon State Park and the Na Pali Coast State Park.
The United States Census Bureau defines Kauaʻi as census tracts 401 through 409 of Kauai County, Hawaiʻi, which comprises all of the county except the islands of Kaʻula, Lehua and Niʻihau. The 2020 United States census population of the island was 73,298. The most populous town is Kapaʻa.
