The zip lines go ACROSS a valley. Doesn’t take much of a drop in elevation to make it work. It probably take just a very short hike up the other side of the valley to make the return trip. A short hike up a valley is pretty easy for the return trip.

That explains how you could get back, but it does not solve the problem of how you get the pulleys that you ride down back to the original side. Also, the photo shows a pretty wicked looking creek down at the bottom.

I think the pulley system has to have a way to pull yourself back up the line when you go home. If I was writing the story, I would have found out and explained it as it is the most obvious question. The idiot reporters of the world have no curiosity anymore.

“but it does not solve the problem of how you get the pulleys that you ride down back to the original side.”

Disconnect the pulley from the eastbound wire, take it with you to the wesbound wire, connect it to that. Downhill all the way.

The pulleys are detachable.

At that height nothing at the bottom looks friendly.
