Dying Light 2Β Oak Windmill is the only Quarry End Windmill you have to activate in the southern neighborhood of the first region on your map. Similar to the previous Windmill we covered (Larch Windmill), the Oak WindmillΒ counts as one of theΒ 17 Windmills featured in the video game developed by Techland.
Therefore, the DL2 Oak WindmillΒ is mandatory to unlock the Don QuixoteΒ trophy/achievement. Obviously, to power up the Quarry End Windmill, youβll have to do some climbing and follow a specific route, which Iβll explain below.
Where To Find the Oak Windmill
As you can see on the map below, the Quarry End Oak Windmill is southeast of the Faction Hub.

What you should know about this landmark is that itβs one of the easiest Windmills because it doesnβt require too much Stamina. Or, simply put, you can activate it very early in the game, assuming you have at least 100 Stamina. So, your first objective is to reach the location on my map.
How To Activate Oak Windmill
Upon reaching the Oak Windmill, it is time to climb to the top. Your starting point should be the wooden board with a yellow tarp on it.

Jump and grab the yellow tarp, then pull yourself up to the wooden platform. Now, turn around, and youβll see a moving weight. Wait for it to reach the bottom, then jump and grab it.
While standing on the moving weight, wait until it reaches the top, then turn around, and youβll see another wooden platform. It is on the other side of the mill, as opposed to the moving weight.

While standing on the second platform, look up, and youβll see another yellow tarp you can grab. Pull yourself up, then go right so you can face the second moving weight, which is a bit smaller. The next step is to jump and grab the smaller side of the weight.

Once you do this (while hanging), move to the left, then turn around. Behind you is the next wooden platform you can jump on. From here, things are pretty straightforward because all thatβs left to do is to slowly walk on the wooden beam around the corner.
Now, keep going around the central structure, and on the other side, youβll see a ladder. Climb on it to spot the DL2 Oak Windmill fuse box you have to activate.

After interacting with the fuse box above, the Dying Light 2 Oak Windmill in Quarry End becomes operational.
