River Crossing

The Uluwehi Falls trail, also known as Secret Falls, offers a truly immersive Kauaʻi adventure that starts with a paddle and ends with a waterfall. You'll kayak up the Wailua River, surrounded by dense rainforest, before embarking on a jungle hike. The path winds through tropical flora, over muddy terrain, and across streams, leading to the stunning 100 to 120-foot "bridal-veil" waterfall cascading into a refreshing pool. It's a unique way to experience the island's interior, combining serene river views with an adventurous trek.

Planning your visit means preparing for a two-part journey; the 1.9-mile (3.1 km) hike with 162 feet (49 metres) of elevation gain is preceded by a significant kayak trip. While the hike itself is rated easy and takes about 51 minutes, the overall experience is considered moderate due to the paddling and often muddy, slippery trail conditions. You'll likely get wet and dirty, so wear appropriate footwear and clothing. Many visitors choose guided tours for convenience, but self-guided options are also popular, typically starting from Wailua River State Park.

What makes this route particularly notable is the required river journey, as the Wailua River is Hawaiʻi's only navigable river. This combination of kayaking and hiking provides a distinct perspective on Kauaʻi's lush landscapes, offering both a peaceful paddle and an exciting jungle trek. Despite its historical name, "Secret Falls," it's a very popular destination, and swimming in the pool at the base of the falls is a highlight for many.
