Goat Simulator 3

Before you can enter the location for this achievement, you'll first need to unlock and equip the Suited Up gear. To do so, head to the store called Lux in the Times Square area of Downtown (location pictured below). Head inside the shop and into the changing room to automatically have this equipped.




Now, in northeastern Downtown, you'll see San Angora marked on your map at a port at the water. In this port are a ton of shipping containers. You're looking for the only black one, on top of a pile, with a "Club Mohair" design on the side of it. Location pictured below. Stand at the door and if you're wearing the suit above, the doors will open (not sure if you need to baa or headbutt too). Once inside, you're in quite a maze to reach the rave at the end. Know that there are two trinkets within this maze, so it's in your best interest to grab them while you're here. The way to the rave is through the concrete tunnels you'll see, following the Xs on the walls, past the people and into the rave. Once inside, this achievement will unlock. Just know to also grab the trinket on top of the disco ball before you leave, so you don't have to come back.
