The place was a little hard to find. Google Maps pointed us to the beginning of a dirt road, and we had to drive about a mile further. (Since then, I adjusted the location on Google Maps.) When we showed up, no one was there, and the office door was locked. Soon a guide showed up. Check-in was easy. Our family of five were the only guests, and there were two guides plus two other staff (not sure what they were doing). Josh and Derrick's lively jokes engaged our three kids. This was the first time our kids did a zipline, and we all felt safe and had fun. We ziplined six times at Lost Canyon, and the short hikes were not difficult for any of us.
I have a grumpy teenage son who just wants to play video games. Beforehand he told me the zipline was a waste of money, but during the tour, he smiled. Afterwards he told me he was glad he went.
The ziplining was shorter than advertised. My confirmation receipt stated the zipline tour was 2:30pm to 5:00pm, but the whole thing (including check-in, driving to the site by 15-passenger van, gear up, safety instruction, training, ziplining, clean up, drive back, and tip) finished at 4:00pm. About an hour of that was ziplining. Probably it was shorter because there were no other guests.
While it was fun, the price (with tip) was not a small sum, working out to about $1 per second of active ziplining. Rafting on the Arkansas (with another company) and zipline (this company) were our favorite of four activities we did in Salida. Our less favorite activities were tubing at Monarch and horseback riding at Mt. Princeton. Rafting (half day) and the zipline were about the same price.
Bottom line, we enjoyed the zipline.
Advice: consider bringing cash for tips (we used Venmo), sunscreen, water, and an action camera. (Some of their helmets already have mounts for action cams.)
