Kauai - The Garden Island
Kauaʻi Visitor Guide
Kauai is Hawaii at its most untamed. Over 90% of the island has no road access — the most dramatic coastline in the state, the Nā Pali Coast, can only be reached by boat, helicopter, or an 11-mile cliffside trail. That inaccessibility is the point. This is the island for people who want jungle, silence, and scenery that hasn’t been manicured for tourists.
Kauai is the oldest and most eroded of the main islands, which is why it looks so different — knife-edge ridges, 3,000-foot Waimea Canyon, waterfalls pouring off every cliff face. It’s also the smallest and quietest of the four visitor islands. No building stands taller than a coconut palm. The pace here is slow on purpose, and the beaches — more coastline per mile than any other island — are often empty.

Waialeale - Wailua headwaters ('Blue Hole') - One of earth's wettest spots
Kauai’s five regions each have their own draw — from the red-dirt canyons of Waimea to the one-lane bridges and taro fields of Hanalei. Hollywood figured this out decades ago (Jurassic Park, South Pacific, Raiders of the Lost Ark were all filmed here), and you’ll understand why the moment you see it.

Our Top Kauai Travel Tips
Kauai is the oldest of the main Hawaiian islands — 5.1 million years of erosion carved the dramatic ridges, canyons, and sea cliffs that define the landscape today. At 553 square miles, it’s the smallest of the four visitor islands, which means less driving and more time at the beach or on a trail.
