My wife and I went ziplining and had a great time! This was our first time ziplining. We are 66 years old, and my wife was having some trouble with the altitude as we are from Iowa which is only around 950 ft above sea level. Our guides, Danny and Madison were great! They were very patient with our small group and made sure everyone was doing okay with the altitude. They made the adventure of ziplining very exciting and fun. We are going back to Castle Rock in August 2025 for a family wedding and if time allows, we will be heading back to The Edge to zipline again.
