The Lighthouse Trailer Park is a location in Watery that players will visit during Alan Wake 2's Return 3: Local Girl chapter. After resolving some business at the nearby Kalevala Knights Workshop, fans will be able to access a Cult Stash at that Trailer Park, though they will need to find a key before they can open. This guide is here to detail the location of that key, and it will help players open the Trailer Park Stash in Alan Wake 2.
