Wailua River

The Wailuā River is a major river on the island of Kauaʻi in the U.S. state of Hawaii. At 20 miles (32 km) long, it is Kauai's largest and longest river[1], as well as Hawaii's 3rd longest river. It is formed by the confluence of its North and South forks just west of Wailua and enters the Pacific Ocean at 22°2′42″N 159°20′11″W. It is the only navigable river (by boats larger than kayaks) in the Hawaiian Islands. It is a center of activity for locals and visitors in the form of boat tours to Fern Grotto, kayaking and water skiing.
