The Garden Isle might be Hawaii’s fourth largest island, but geologically, it is the oldest of Hawaii’s main islands, formed approximately five million years ago. It seems obvious then, that the oldest rivers in the Aloha State would be found here on the stunning island of Kauai. Meandering through the heart of Waimea Canyon, the Waimea River is not only a fascinating piece of living history but one of the most breathtaking rivers we’ve ever seen.

Located in western Kauai, the Waimea Canyon is often referred to as the “Grand Canyon of the Pacific,” and though the expansive canyon is not as big — or as old — as its Arizona cousin, you will surely never experience anything quite like this geological wonder in Hawaii.

At ten miles long, a mile wide and approximately 3,600 feet deep, the Waimea Canyon is home to plants and trees of all shapes and sizes, as well as the jaw-dropping Waimea River.

The valleys of the Waimea River and its tributary, the Makaweli River, were once heavily populated by native Hawaiians, but are now just stunning pieces of living history showcasing not only the geological formation of Kauai but its human history as well.

While Waimea Canyon State Park is one of the most popular tourist destinations in Hawaii, the Waimea River is often overshadowed by Hawaii’s other fascinating bodies of water. So, the next time you visit this stunning spot, be sure to soak in the beauty of this ravishing river.
