Kauai is nicknamed the "Garden Isle." The island is most famous for Waimea Valley, which is referred to as the "Grand Canyon of the Pacific."

Visitors can take mule rides passed the sea cliffs and up to the former site of the leprosy colony at Kalaupapa peninsula.
Lanai is known by many as the "Pineapple Isle" because, according to Maui Revealed, throughout most of the 20th century, 98 percent of the island was owned by Dole Pineapple.

Niihau is considered the "Forbidden Isle." It is the smallest of the inhabited islands and is a privately owned island owned by the Robinson family. Niihau is off limits to visitors, although there are a limited amount of boat tours that do visit the island.
Kahoolawe was once used by the U.S. military for target practice. Because of this, the island has been nicknamed by locals as the "Target Isle." Today, it is undergoing restoration in the hopes that it will one day serve as an educational center on native Hawaiian culture.
