The track has few bends and is moderately wide. There are three craters each containing a magma lake around the U-bends. If racers collide with them collectively enough times, they trigger an eruption which covers the track with magma. Any racer boosting over magma gets burnt and slowed.
There are four vents on the course, two on the floor and two on the wall. Shortly before the vent activates, it will either emit a small plume of steam or a small flame and the vents will either emit a plume of steam shortly after, or a jet of flame, respectively. The flame jets burn and slow racers moving across them, the steam jets propel them over or into walls to either help or hinder a racer, which is determined by whether it's on the floor or on a wall.
Fire is one of the Top Ride courses in Kirby Air Ride. The course has unpredictable vents which either provide short cuts or burn the player, and colliding with magma lakes build up to an eruption which spills lava all over. Its alternate unlockable track is King Dedede's classic theme.
