Guided Kayak and Hike to Secret Falls Kauai

The Wailua River by kayak

The Wailua River winds from the mountains of the east side of Kauai to the coast near Kapaa. In Hawaiian history it was a sacred place, and the valley still feels quiet and green, lined with hau trees, ferns and steep ridges. Paddling it by kayak is a gentle way to see this landscape, and the current and the guide keep the route simple even for beginners.

On the water you are likely to see egrets and other river birds, and the guide points out plants and landmarks as you go. The first stretch of the tour is a steady paddle of a short distance, so a Wailua River kayak trip is a good choice if you want a calm start to your day before the hike.

The jungle hike

After you leave the kayaks, the guide leads you on foot into the forest. The trail passes through thick tropical vegetation, crosses streams and climbs over roots and rocks. Parts can be muddy or slippery after rain, so good footwear matters and a moderate level of fitness is needed. Expect a walk of roughly a few kilometres in total, with stops to rest and look around.

The hike is the most physical part of the Secret Falls tour. Take your time, drink water before you start, and follow the guide's advice on where to step. Mornings are often cooler and quieter, while the early-afternoon departure suits those who prefer a later start.

Secret Falls and the swimming pool

Secret Falls, also known as Uluwehi Falls, drops about 100 feet into a deep pool surrounded by forest walls. It is among the best-known waterfalls on the east side of Kauai and is reached only on foot or by a river trip like this one. The cool pool is a rewarding place to swim after the hike.

The size of the flow changes with the season and the recent rain: winter and rainy weeks bring heavier falls, while summer can be calmer. The guide decides whether swimming is safe on the day, depending on river levels. If you are asking whether the Secret Falls hike is worth it, the swim at the end is the reason most people say yes.

Planning your Secret Falls adventure

The tour lasts about five hours and runs at two start times, so check the booking panel for dates. Kayaks, a dry bag and safety equipment are included, and the guide speaks English. Food and drinks are not included, so bring water and a snack.

Wear swimwear under quick-drying clothes and secure shoes that can get wet, and carry reef-safe sunscreen and insect repellent. A change of clothes and a towel in the dry bag are useful for the ride back. The minimum age is eight, and the guide sets the pace so the group stays together on both the water and the trail.
