It is easy to get into the flow here, especially with a day trip down the Wailua River on Kauai’s north shore. I booked a day trip with Kayak Kauai for a guided tour to the Secret Waterfall (known to locals as Uluwehi Falls). We launched in Kapa’a and stroked steadily along a wide dark green river inland, away from the demanding Pacific. The landscape was flat at first, and then riversides rose into black rock and tree-covered cliffs.
