Kauai Island is geologically the oldest of the main Hawaiian Islands, approximately six million years old. Kauaʻi’s origins are volcanic, the island having been formed by the passage of the Pacific plate over the Hawaii hotspot.
The highest peak on this mountainous island is Kawaikini. On the west side of the island, Waimea town is located at the mouth of the Waimea River, whose flow formed Waimea Canyon, one of the world’s most scenic canyons.
Kauai is one of the wettest spots on earth. But it does not rain all day and everyday, be sure that the rain will not ruin your vacation on Kauai Island. The high annual rainfall has eroded deep valleys in the central mountains, carving out canyons with many scenic waterfalls. ↓
