While not many Kauai homes are located along the Wailua River, the river is one of the longest rivers in the state and is the only navigable river in the Hawaiian Islands. Beginning at the crater of Mount Waialeale, the river runs towards its mouth that meets the Pacific Ocean. A hub of activity and social life on the island, both locals and tourists can be spotted along the river most days of the year. The river caters mainly to kayak tours that run up the river. The tours take participants up into the deeper Kauai forests to explore the waterfalls and natural sights that are hidden the in the lush brush beyond. Boat tours to the Fern Grotto and other water activities like jet skiing, banana boating, and parasailing are also based at the mouth of the Wailua River.
But besides the variety of activities available on the river, Wailua River has a number of attractions itself. Halokila Hawaiian Village is one of the biggest sights along the waterway. The village is a complex of ancient Hawaiian buildings and homes. A bird refuge also is located along Wailua River and attracts a number of endemic species that are quite frequently spotted by kayakers passing by. A waterfall referred to by the simple name of “Secret Falls” is also popular for its rope swing and gorgeous vistas.
