I went there with my three adult children (19, 24, 26) on July 19th 2018 and thought the overall experience was fantastic. The guides were awesome and I would not recommend taking the trip without them. Also, the provided lunch was pretty good!
I would like recommend that they make it clear somewhere, that if you make a reservation
on-line, the address on the website is different then where you need to arrive for your trip departure (but maybe I missed it).
The river was challenging enough for someone with experience, but not too crazy for a rookie!
