Craggy Cliffs is a fairly well-known location in Fortnite, but if you've only recently started playing, you may struggle to find it. Craggy Cliffs used to be a major location in the game, but later seasons have flooded it, and it's no longer a named location. Now that it's just a waypoint, it's no longer marked on the map, so new players may have trouble getting there.
You can find steep cliffs on the north coast of the island, near the yacht. It's still very flooded, but there are buildings you can enter now that the water has started to come down. It's not the best place to go right now, as loot and ammo boxes are limited, but it's close to the yacht where you can find a lot more stuff, and even a helicopter to use to access a best part of the map.
The radio tower helicopter has been removed, so you won't be able to go there to find one, but there's still plenty of loot if you still need weapons when you're done in Craggy Cliffs.
You will need to head here during Week 5 of Chapter 2 Season 3 to do a fishing spot. The bad news is that with limited loot it can be difficult to get a fishing rod here, so we suggest you head to the yacht first, grab a fishing rod which is a spawn common there, then make your way to Craggy Cliffs to complete the challenge.
