This experience was amazing from beginning to end! The ATV ride to the zip lines was so fun. Our guides were Olivia and Jackie and they were fantastic! They were super funny and really knowledge and I felt completely safe in their care while ziplining. While ziplining, there is little to nothing you need to do. The guides do all of the clipping and they even help you to slow down stop on the other side of the line. The walks to each platform can range from a small uphill hike, ladders, to plank bridges. Overall, this was an incredible experience and I recommend it to anyone visiting Denali!
