This challenge is part of Fortnite Season 3 Week 5 Challenges and you'll have to catch five fish at Craggy Cliffs. At the time of writing, the old Craggy Cliffs location is no longer on the map and for good reason: the port city was completely flooded at the beginning of the season!
Map
The now partially sunken city is located in the north of the island, next to Pleasant Park. This challenge will be rather complex in the 48 hours following its publication, since the next drop in the water level will only occur later!
Also, most of the buildings on the site are still inaccessible and submerged. This leaves you less chance to find a Fishing Rod or Harpoon, which will allow you to complete the challenge.
