Unwelcome Guest is a Prepper Stash in Far Cry 5. Prepper Stashes are mini-quests that offer exceptional rewards for completing.
Location[]
This stash starts at Frank's Cabin on the edge of the map, west of Langford Lake in Whitetail Mountains.
Finding the Stash[]
Search the area (more so to the left) and look for bloodstains on the ground. Close to this is a cave entrance with a bear inside. Kill the bear and take the keycard that is next to the corpse. Take the key back to the cabin and use it to get inside.
Rewards[]
The stash includes cash and perk magazines.
