Fortnite Grill Locations
Grills are scattered all over the map, and you can generally find them in obvious places. Look for them in backyards and near picnic/camping sites. Here's what the grill looks like:
For exact locations, I've gone through the map and tagged a bunch of their exact spawns. Keep in mind, there might be even more spawns available, but you only need to destroy seven of them, so this map should more than suffice.
You'll notice a great majority of them are located on the south eastern side of the map. This is going to be the best place to go and farm them if you want to destroy them in one match! Don't forget to have your Low 'n Slow pickaxe equipped, or you won't get credit when smashing.
