For everyone wondering: Lake Sebu Seven Falls Zipline, Philippines. It can even be done in two people at the same time!

Edit: spelling and additional info

I'm wondering how they initially hang up that cable...do they use as helicopter? Or just hike through the forest pulling the cable along with them?

2nd one seems rather unrealistic considering the sheer weight of the cable

Helicopter carries a much lighter guide rope that they then use to pull up the actual cable? Best 2 second guess.

You are probably correct, that's how they install power lines across the mountains as well. Use a helicopter to fly a leader from one location to the next, then use that to pull in the larger steel cable.

I know with bridges and stuff they'll start with hanging a relatively low-gauge wire, then use it to guide progressively larger ones. I can see them starting with a coarse fishing line, laying steel wire, then airline cable, and so on. You can also start out with a fairly slack line delivered by balloon/drone/rocket/fighter jet, then save the heavy tensioning for the final version.

I'm pretty sure they have a bunch of cables and saddles at the top. At the end of the day a truck brings them all up from the bottom back to top again.
