I think the whole zip line lasts about 1 hour, depending on the amount of people, there were only 2 of us plus the 2 guides at the time we were there. The platforms are one after another, I guess if you want to stop and take pictures, that would fine, but if you have a line of people behind you, I dont think they would want you to hang out. The platforms are only about 8ft wide. Once you do the hike, you dont reach ground until the end. You are pretty much in the trees the whole time, so you could also say, there is no turning back. So, you do have to be ready.
