In LEGO Fortnite, caves are the secret to unlocking tons of ores and finding valuable treasure chests. The Lost Isles are no exception, with its caves holding several new gem types used to craft upgraded versions of the Flint-Knock Pistol, Throwing Spear, and more.

Where to find Lost Isles caves in LEGO Fortnite

Caves spawn randomly around LEGO Fortnite’s Lost Isles world, much like they do in the regular mainland areas. The exact spawn locations depend on your world’s seed, so one map will differ from the next.

Despite this, there are two things to look out for: cave map icons and peculiar-looking stone formations. Watch for raised stone hills with decorative pillars and clay pots around as you run, drive, and fly around your world. Combined with a large opening on the rock’s side, these lead to one of many caves or grottos you’ll find around the map.

You’ll also want to check your map occasionally for cave icons. It’s easy to miss them, especially if you’re focused on reaching another destination or don’t notice a hidden cave somewhere. If you’ve been running around for a while, open your map and see if a cave image appears anywhere. If not, keep running around and hope for the best.

Once you find a cave, entering it will lead to an underground cavern full of your usual granite and marble deposits. Along the way, you’ll find gold and rough emerald veins, which you can harvest and turn into gold bars and cut emeralds to upgrade your weapons. Fortunately, they’re pretty common in these caves, so you shouldn’t have too much trouble spotting some. Just try not to get lost, as getting out can be a pain sometimes.
