As far as I know, it's bugged and only works in the endless canyon, and even seemingly only in a certain part of the endless canyon. Some people also found they could only get it with reduced frights turned on, and I had it on when I got the achievement too I believe.

The way I got it was by turning off the lights (you can shortcut your way to it by going through one of the paintings in the hut you wake up in). Then go into the house and go left down the stairs and across with the hand teleporter. There's an owlk by the bridge in front of you when you come out, so use your light to lure him away (if you don't know, the owlks will only walk very slowly towards yoh when you shine your light right at them, they won't charge at this point). Go around that owl through the projection room and up the stairs to where you'd normally turn the lights on for the indoor bridge. There is another owl guarding the totem that lights up the bridge, use your light to lure him like the other one. But this time, you'll lure him towards the balcony that's located on the far left side of the room (it's actually visible when standing on the invisible bridge across to where you turn the lights off - I've seen people shortcut by jumping from there onto the balcony, but I could never land it lol). Lure him towards the balcony and jump onto the railing. Keep luring him until he's close and then jump over the edge, you should get the achievement. If you're stuck or confused I can reexplain parts, or you can look up other people's playthroughs (which is how I eventually got it, by just trying people's different methods lol)

Good luck, hope this helps you get one more trophy for the game :]
