It's hard to find activities for our whole family to enjoy as our youngest is 5 and our oldest is 16. We all had a blast at Denver Adventures zip line tour. We did the 6 zip line tour. It was the perfect amount of time. One of zip lines had a hike that was a little challenging for our 5 year old, but she managed her way up with some help from Dad. Our guides Sam, Callie and Brian were awesome. They were fun and entertaining while at the same time making sure we were safe and comfortable with the instructions. It was a great way to have fun while out in nature. We even saw some moose nearby, which was amazing (and rarely happens). I would highly recommend this zip line tour.
