From laid-back yet cosmopolitan O‘ahu to wild Moloka‘i, Hawai‘i is as diverse as the travelers who visit. Within the 137-island archipelago are six main islands that entice visitors with verdant jungle, dreamy white-sand beaches, active volcanoes, and opportunities to learn about the long, rich culture of Native Hawaiians, which dates back more 1,000 years. Natural beauty and outdoor adventure are available on every island, but some are easier to access and others quieter and less crowded.
