Stardust Fields is a rectangular shape with many [huge] fallen stars. Stardust Fields also has many fallen stars which can land on the field to act like regular Stars.

Peach's Castle Grounds is a large stage that appears at the base of Peach's Castle. The stage is pretty much an exact replica of the castle's grounds from Mario Kart 64/Super Mario 64 (including the turn-off onto Royal Raceway, which is blocked off). Toads, Goombas, and Shy Guys are in the crowd (behind the blockade of Royal Raceway and on the cliff).
The players can battle in the lake, in the moat or on the land. The door of the castle is also open, so players can go into the main room of the castle. Bowser's laugh can be heard while entering the castle, and MIPS can be seen hopping around the outside.
Dimble Clearing is a clearing within Dimble Wood. Many Treevils appear in this place, and they walk around. There is also a small section of mud. Dimble Clearing has literally no obstacles (except for the Treevils, but they act as walls).
Dimble Clearing includes many Wigglers, Sockops, Scutlets and Leaf Guys sitting on the trees. Dimble Clearing resembles a spring-version of the track Maple Treeway from Mario Kart Wii.
Bowser's Lava Lair is a spooky battle course area inside of Bowser's Castle. Bowser's Lava Lair is basically a large area inside of Castle Grounds with three lava pits with gates over top.
Many Koopa Troopas, Peepas, Goombas, Draglets and Hammer Bros. can be seen standing on top of the walls. Along with the enemies in the crowd, Wallops walk around the stage and act as walls. They can, however, be knocked over by hitting it with an item (which can crush a person underneath it and flatten them). Podoboos also jump out of the lava pits.
Delfino Plaza is a tropical town on Isle Delfino. The Stage, although the battle arena is medium-sized, the stage as a whole is large. The stage is an exact replica of the Delfino Plaza from Super Mario Sunshine, right down to having the M insigna left by Shadow Mario. Many Piantas, Nokis and Toads are seen on boats in the background, and Dolphins can be seen swimming around.
Players can battle anywhere in the plaza, there is also a jump over the docking area, where some Item Blocks are located.
