Although week 10 includes two missions related to special sand castles, one that asks us to build and another to destroy, in this case we are going to focus on the first to find out where and how to build special sand castles .

Although there may be more sand castles scattered around the Fortnite beaches, the easiest group of castles to find is the one to the west of the island, on the Rainbow Rentals beach. Here you have a map with its exact location .

To complete the challenge, all you have to do is go to that area and press the action button on the invisible sand castles on that beach. You need to build 3 special sand castles to complete the mission.
