The darkest, most dangerous region in Mario Kart World's Free Roam? Well, it's got to be that dark, ashen region in the northwest, right? Home of Bowser? Residence of a big volcano? Yep, that's the Lava Region for you.
Between Bowser's Castle and Toad's Factory, there's lots of boiling magma to avoid and collectibles to discover. We'll be going over where all of those big blue buttons and Peach coins are. But don't forget, there are plenty of other regions and courses to explore, so have a look through our P Switch and Peach Medallion hubs to see our regional map breakdown and guides for all sections of the world.
P Switch Missions - 'Lava Region'
'Lava Region' P Switch Map
The Volcanic Region covers the entire northwest dark area in the corner of the Mario Kart World map. That means there are Airship Fortress, Bowser's Castle, Dry Bones Burnout, and Toad's Factory are all to be found here, alongside a whole load more covering the ashen areas and volcano.
It's a spicy one, so make sure you take this map with all 46 P Switch locations with you!
