For this week's Fortnite epic challenges, you need to visit Coral Cove, Base Camp Golf, and Unremarkable Shack. This is part of Season 7's alien-theme, with ongoing challenges such as finding the unlock Kymera skins.
Fortunately, you don't have to hit all of these locations in a single game, especially as the locations are quite spread out. Coral Cove can be found on the small island to the west of Coral Castle. Base Camp Golf can be found southeast of Catty Corner, on the snowy mountain. Unremarkable Shack can be found on the small island northwest of Craggy Cliffs.
Here's a map to show you the exact location of each landmark, it's worth noting that these locations aren't named locations on the Fortnite in-game map, so you need to know where to head before diving in. These areas aren't likely to be highly contested after the initial rush of people wishing to complete this challenge, but you can't be too careful, so be sure to go in brandishing the best new plasma cannon.
