Daisy Circuit is the first course of the Star Cup in Mario Kart Wii. It is a seaside resort. The course travels across a seaside town with a sunset background on a shore. The course follows Daisy's appearance, with various flower motifs found throughout the level. There is also a docking area with a lighthouse and cruise ships; some of which mimic the appearance of Daisy Cruiser from Mario Kart: Double Dash!! Small baroque-style buildings can be seen from the background. On the track there are two circular fountains. On the top of the first fountain is a large golden statue of Daisy and Luigi dancing. The other statue shows Baby Luigi swinging Baby Daisy.
The course takes place in a small town near the ocean at sunset, and Daisy Cruiser can be seen in the background. Cones act as simple obstacles and slow players if they run into them. Two fountains are in the middle of the course which must be driven around.
The track begins rather straight leading up to a sharp right hand turn into the town, where Toads, Piantas, Boos and Sledge Bros. line the streets. The road is slightly twisted and has cones.
After the town are the two fountains of Daisy and Luigi and their baby counterparts. When the player is playing as a Mii, the heads of the statues are replaced by Mii heads. Daisy and Baby Daisy are replaced by female Mii heads, while Luigi and Baby Luigi are changed to male Mii heads. Racers are able to go either right or left of the fountains around them. There are item boxes around the second fountain for players to grab. After the fountains is a small tunnel which gently flows to the right. Miis are present in this tunnel, cheering for the character. Right after the tunnel is a straight road that leads to a large hairpin turn around the lighthouse. Soon after this is another straightway that leads to a left hand turn going back to the start and finish line.
A small shortcut can be taken here by going into a narrow staircase in the pink building. Since it is offroad, it slows the player if the player manages to go into it and a Mushroom is required. Boost panels and an item block are in the shortcut.
In Mario Kart Wii, the staff ghost is Daisy on the Daytripper with a time of 1:56.822. If the player completes Time Trials on this course in 1:51.786 or faster, they will unlock the expert staff ghost (Daisy on the Mach Bike with a time of 1:41.362).
A tournament took place on this track, where players had to pass through a total of 22 gates. This tournament was the second one for October 2009, and it was repeated as the first tournament of August 2011, the second tournament of October 2012, and the first tournament of January 2014.
Official European website: "The roads of this seaside resort have been closed so you can tear round the tight turns and through the tunnel at top speed. Don't let the crowd down!"
This is one of the two tracks in Mario Kart Wii to be fully enclosed and not feature any hazards, the other being Luigi Circuit.
Despite being a Circuit track, Daisy Circuit does not use the main circuit theme of the game (i.e. Luigi Circuit and Mario Circuit). Instead, it has its own unique theme to fit the seaside setting, which has some parts of the main circuit theme remixed.
The Daisy Cruiser that appears in the background scenery has its exhaust pipe colored gray instead of orange.
