There were eleven zip lines....the last 4 were experienced in the pouring rain, and we still had fun! You go a lot faster, though, when the lines are wet, and we all had camouflage on our faces from the water that dropped on us as we zipped from place to place. It is a 15 (20 for me) minute hike, mostly up, to the place where you begin the actual ziplines. I felt amazingly safe and the workers were conscientious and helpful. It was a great experience!
