Uluwehi Falls, also known as the ‘secret falls,’ are found deep in the rainforest of the Wailua River area on Kauai. Getting to Uluwehi Falls is an adventure in itself and can only be done by kayak and hiking.

Many kayaking tours are available that will provide you with all the gear you need and an interesting tour of the area. It is recommended to join one of these tours, as they will also be able to provide helpful information about the weather and current conditions.

Understanding the weather conditions is important because the river can be quite challenging to paddle on some days. A standard paddle will take about 45 minutes. If you prefer to hike, the trail is mostly flat. You will walk along the river bank and even get to use a rope to help you cross some rapids!

Regardless of how you get there, Uluwehi Falls is a fantastic sight. The waterfall is over 100 feet tall, and the pool at the bottom is perfect for swimming. Make sure to bring your camera to capture this natural wonder!

Viewable from the road about three miles up Maalo Road, north of Lihue, Wailua Falls is a must-see for any visitor to Kauai. And for those looking for a little bit of adventure, during ancient times, Hawaiians used to take the 83-foot drop as a test of bravery and adulthood – though we do not recommend doing that today!
