Fallout 76: Go to the Raider Cache - Key to the Past

Go to the Raider Cache is an objective in Fallout 76 (F76).

Quest[edit]

Once again, head back to the Pleasant Valley Ski Resort, but this time you want to head to the main lodge.
Once in there, head up the stairs, going onto the walkway over the check-in desk.
Go on up the ramp and head over into the stair well.
In here, you will want to take the stairs downward.
Go to the very bottom of the area to find the door you are looking for.
You will find an Employee's Only door.
