Our guide, Zach, was the best! He had the best dad jokes and definitely loves his job and it shows! Shared lots of information about the flora, fauna and history of the island as we did the couple mile kayak up to the mile hike to the secret waterfall. Took a dip in the secret waterfall and had a picnic. It was truly a magical experience and would highly recommend this trip to anyone. It is pretty strenuous as you will be paddling up river for a couple of miles and the hike is quite muddy, like walking on uneven rocks and clay, so just be aware of that, otherwise, it was the highlight for me on my trip to Kauai!
