How difficult is the hike to Uluwehi Falls?
The 1.5-mile hike is moderately difficult due to thick mud and slippery stream crossings.
The path to Secret Falls is notoriously muddy. You will encounter multiple streams that you must cross on foot. The rocks in the water are often hidden and slick. Heavy rains, especially in winter, make the mud much worse.
Do I need a kayak for the Secret Falls hike Kauai?
Yes, you must paddle 2 miles upstream on the Wailua River to reach the trailhead.
There is no road access to the start of the hike. Visitors must rent a kayak or stand-up paddleboard, or book a guided tour. The paddling portion requires physical exertion before the hike even begins.
What shoes are required for the trail?
You need water shoes or hiking sandals with ankle straps and a strong grip.
Do not wear flip-flops. The deep mud will pull loose shoes off your feet. Barefoot hiking is dangerous due to sharp rocks during the stream crossings. Closed-toe shoes or sturdy strapped sandals are the safest option.

Are there any trail closures in 2026?

Hurricane Lowell caused damage to the area. While the Wailua River remained open for paddling, specific hiking routes faced temporary shutdowns. Check local state park notices before planning your trip.
Is it safe to swim at the waterfall?
Swimming in the 120-foot waterfall pool is permitted, but comes with specific health risks.
The primary risk is Leptospirosis. Never swallow the river water. Do not swim if you have open cuts. Pay attention to flash flood warnings, as streams can rise rapidly.
