I booked this tour for myself and was in a small group just with another couple. I didn't realize this tour is outside of the park but was so pleasantly surprised with such a unique and fun experience. Our guide, Kade, was amazing! He was so helpful, made us feel safe the whole way, and really made the experience what it was. The 4 hour length of the tour was the perfect amount of time as it left time to do some more exploring in and out of the park afterwards. I'm absolutely recommending this tour to friends and family.
