Location of safes in FortniteTo validate this challenge and unlock the 20 XP, Epic Games asks you to search three safes, which can be done very easily in one game, provided you know where to look.
As you can imagine, we very often find them in the so-called places, which is why we advise you to favor these areas. Five towns have three or more: Sweaty Sands, Holly Hedges, Craggy Cliffs, Pleasant Park, and Dirty Docks, but you'll find safes all over the island.
To help you in your research, here are their locations in said areas:
You can also take help from fortnite.gg, which will show you more safe locations, if those in major cities have already been opened, for example.
Safes can be very advantageous, since you can, in particular, recover many gold bars, useful for certain things in the battle royale.
