We had a great experience on the 12-line tour. We had 3 adults and 4 kids (ages 11-14), the hike up is a little steep, but not that long, so totally doable. The kids and adults had the best time, the staff was on top of it and very professional, but also super fun. We went with Cameron and Snow who did a great job with the kids, made everyone comfortable, where really funny and taught the kids a lot of cool stuff about the mountains and the surrounding area. I highly recommend this if your up for a little fun that outside of the norm! My only advice is to take your own water bottle with clip to snap on to your harness! You'll be glad you did - it was hot while we were there in mid-June!
