Island Overview

Kauai is the fourth-largest of the Hawaiian Islands and is often called the “Garden Island” because of its lush rainforests, dramatic cliffs, and abundant waterfalls. It lies about 73 miles (117 km) northwest of Oahu and had a population of around 73,000 people as of 2020.

  • Hubs: Main population centers include Līhuʻe (the county seat) and Kapaʻa, the island’s largest town.

Nature and Geography

Kauai's geography is defined by its age and extreme weather patterns. As the oldest island, erosion has sculpted deep canyons and sharp spires that are unique in the archipelago.

The Peaks

The highest peak is Kawaikini at 5,243 ft (1,598 m), with Mount Waiʻaleʻale nearby, one of the wettest places on Earth with about 460 inches of rain annually.

Waimea Canyon

Often called the “Grand Canyon of the Pacific,” this massive chasm is about 3,000 ft (910 m) deep, offering striking geological contrasts to the lush North Shore.

Regions of Kauai

Each side of the island offers a distinct microclimate and set of experiences. From the arid west to the rainy north, Kauai is a world of contrasts.

North Shore

Home to the world-famous Nā Pali Coast, beautiful beaches, taro fields, and expansive botanical gardens. This is the spiritual and aesthetic heart of the Garden Island, where the road ends at the gateway to the Kalalau Trail.

East Side (“Coconut Coast”)

Lined with palm trees and golden beaches, the East Side is the island's central artery. It offers accessible hiking, the Wailua River for kayaking, and a bustling local community.

South Shore

Known for its sunny resort areas and top-rated beaches like Poipu. When the North is rainy, the South usually offers reliable sun and calmer waters during the winter months.

West Side

Features the dramatic Waimea Canyon and the historic landing site of Captain Cook. It is the arid, rugged counterpart to the lush interior, offering vast vistas and sunset views over the island of Niʻihau.
