We recently visited Denver for the first time and wanted to see what all it had to offer. Neither one of us had ever been zip lining and figured, "Hey we're in Colorado, what better time to go?" I called and was told they had to reach the minimum number of participants to go out for the day. (We were the only two booked for that time) It was our last day in town and I made them aware of this. About an hour later I get a confirmation email that we are a go. Upon arrival the receptionist Annie informs us they didnt meet the minimum participants but they would still take us out on a private tour. Talk about winning a customer over from the start! Our tour guides were Alex, Chris and Patrick. The guys were great from start to finish and really made us feel comfortable in every situation. Plenty of safety tips, do's and don'ts, and humor to boot. Afterwards we had a hard time getting a ride back to the Denver area and Annie offered her services for a small fee, which also came with all sorts of knowledge about Colorado and the area. I would definitely book with these guys again. You guys rock!
