Our family of 6 had a fabulous time with our guide Kai. The trip itself is gorgeous but Kai made the trip even more awesome. He knew everything about Kauai history, customs, wildlife, plants, best places to eat, making the trip more special. The kayaking is a bit challenging on the way back due to headwinds but totally doable. The hike to the waterfall is easy. Our 16, 13, 10 and 7 year olds had no issues but definitely needed to have the younger two grouped with a stronger kayaking parent. Highly recommend!
