Horizon Forbidden WestΒ Plainsong Vista Point is found in the second area Aloy explores while heading west, and it follows the same logic as The Daunt Vista Point. However, the HZFWΒ Plainsong Vista Point is a bit trickier because to find where the image was taken, or the Plainsong Vista Point image location, if you want, youβll have to do a bit of exploration.
Nevertheless, theΒ Horizon 2 Forbidden WestΒ Plainsong Vista Point is mandatory for completionists since it counts as one of the 9 Vista Points in the video game developed by Guerrilla Games. So, letβs see how to solve this puzzle.
Where To Find the Plainsong Vista Point
HZW Plainsong Vista Point is west of Plainsong or the settlement youβll first visit when you play The Dying Lands main quest. The said settlement is essential in Aloyβs story, but you can visit the Plainsong Vista Point beforehand. On my map below, you can observe the Vista Point in question.

Upon reaching the location on my map once more, youβll want to find the Plainsong Vista Point Pillar and scan it. The Pillar, in this case, is on a small hill. Make sure you dispatch the machines nearby before, though. Once youβre done, head to the front of the Pillar and scan the attached plaque.

Great! Now, the Vista Point: Plainsong quest should become available, and once more, youβll need to find where the image was taken.
How To Find Where the Plainsong Vista Point Image Was Taken
After triggering the quest, youβll have to head south from your current location near the Pillar. In other words, youβll have to follow the path up the mountain nearby.
As you progress, youβll see two satellite dishes (or whatβs left of them); however, the actual location is above them. For this guide to be as helpful as possible, below, you can see the location where the picture was taken. Thatβs the spot youβll have to reach.

What you should know about this location is that Skydrifters heavily protect it, and youβll also have to climb the mountain wall behind the satellite dishes. Youβll most likely notice several old buildings on top of the mountain. When you get to the spot on my map, check the ruins on the right side while facing the dishes and the valley below.

Place Aloy in the exact location as the one in my image above, then press the right thumbstick. Now align the hologram on her Focus with the structures in the distance. You may want to use the central building to do it faster.
When the hologram and the three structures are aligned, the Horizon II Forbidden WestΒ Plainsong Vista Point puzzle is complete, and youβll receive 1500 XP, so now you may want to travel further west and solve The Long Coast Vista Point.
