Very fun! Our tour guides were Heath, Tony, and Sam, they were all great and made the experience really enjoyable. Be prepared for a few short, steep-ish hikes to get from one line to the next in the first half, second half is all downhill (for the 6-line option). Loved all of the lines, there is a good mix of fast/slow/short/long and the views of the Colorado mountains are fantastic. Would definitely recommend to a friend or go again myself!
