Wailua River & Uluwehi Falls (Secret Falls) - description

The Wailuā River is a river on the island of Kauai. It rises at Mount Waiʻaleʻale and is the only navigable river in Hawaii. Mostly, however, only kayaks can be found there.

The 32-kilometer-long river, which once flowed along seven different Heiau (temples) flowed past, has its origin in the center of the island on Mount Waialeale, which is over 1,500 meters high. The Wailua River includes two popular waterfalls: Opaekaa Falls and Wailua Falls. You can explore the scenic river itself by kayak, SUP board or outrigger boat. Boat tours are also available. In addition, there are guided trips to Fern Grotto, a cave made of natural lava rock. This romantic area is also a popular spot for weddings. Also look out for the Nounou Mountains, a mountain range between Wailua and Kapaa that resembles a human figure lying on its back and is therefore called the Sleeping Giant.

You can also see the river from your car. To do so, follow Kuamoo Road (Hwy. 580) coming from Kuhio Highway (Hwy. 56) along the north bank of the river inland. 

In 1946, a Hawaiian named Walter Smith Sr. came up with the idea of offering boat trips on the Wailua River. It all started with a borrowed motor and a small rowboat. Interested tourists were taken along the beautiful scenery to a huge grotto covered with ferns (Fern Grotto).

The company became a success story and today, almost 70 years later, the boat business is run by the fourth generation of descendants. The rowing boat has become large professional open-air boats and the fern-covered grotto in the heart of the Wailua Marina State ParksThe Fern Grotto is one of the most popular destinations for Kauai tourists today.

The tour is still run by Smith`s today. The whole trip takes about 1.5 hours and costs 20$ for adults and 10$ for children. Boats depart daily at 9:30am, 11:00am, 2:00pm or 3:30pm.

Admittedly, you have to like the kitsch factor of the boat trip, because on the "Journey of Songs and Legends" there is hula dancing, schmaltzy singing and ancient Hawaiian stories. So it's much nicer to rent a kayak to explore the river and waterfalls for yourself.

What we say

I am a big fan of self-exploration. You have more time, are not bound and can discover and linger in their own way. I have already done this kayak tour 2x because it is so beautiful. For 35$ you can rent a kayak at "Kamokila Hawaiian Village" and explore the river on your own. After 30 minutes of paddling, you will reach a small forest with a dock, from where you can hike about 45 minutes to Uluwehi Falls (also known as Secret Falls). It is recommended to bring hiking sandals. The path goes through beautiful nature along the Wailua River, you also have to cross the river (there are ropes to help). The waterfalls are beautiful (but often well visited). You can also take a bath in the pool of the waterfalls. If you like wakeboarding, you should treat yourself to the expensive fun (100$ for 30 minutes) in the evening sun around 4:00 pm. A pleasure of the unforgettable kind.

  • Exploring the Wailua River on your own
