What to expect on Uluwehi Falls loop from Wailua River State Park

Your journey to Uluwehi Falls, often called Secret Falls, begins with a leisurely paddle up the Wailua River, Hawaiʻi's only navigable river. You'll glide through lush rainforests and verdant valleys for about two to two and a half miles before docking your kayak. From there, the trail continues on foot through dense jungle, where you'll navigate muddy, uneven paths with exposed roots and multiple stream crossings, some potentially thigh-deep. The reward is the magnificent Uluwehi Falls, a "bridal-veil" cascade plunging 100 to 120 feet into a refreshing pool, framed by tropical foliage. Expect to get wet and muddy; this trail is best suited for those who embrace a bit of ruggedness.

Planning your visit

Accessing Uluwehi Falls requires both kayaking and hiking, making it a distinct two-part adventure. While the hiking portion is short, the overall activity is often rated easy to moderate due to the paddling and potentially challenging trail conditions. Good fitness and appropriate footwear are highly recommended, as the path can be very slippery, especially after rain. Be aware that flash floods can be a risk during or after heavy rains; do not proceed if water levels are high or fast-moving. Many visitors opt for guided tours, which often include equipment and assistance, though self-guided options are available. Parking is typically available at Wailua River State Park, where you'll launch your kayak.
