Peach Beach is Princess Peach's personal race course in the game Mario Kart: Double Dash!! for the Nintendo GameCube and also in Mario Kart Wii for the Wii. The beach is reminiscent of Gelato Beach and other areas from Super Mario Sunshine, and is Peach's favorite beach resort.
The race course starts out at a cobbled street that looks like Delfino Plaza. Near the starting line there is a billboard depicting Peach on it. She is holding a parasol and has her hair tied back. There is also a billboard with Toad on it. When entering the beach in a Ricco Harbor-like area, the Daisy Cruiser can be seen in the background. In the harbor, another cruise ship can be seen. It is stated in the official guide for Mario Kart: Double Dash!!, that this cruise ship in the harbor (the Sunshine) belongs to Peach. Also the Pianta Statue fountain is replaced by a huge Power Star in Versus mode. While racing on the beach, wandering Cataquacks of four different colors will charge at the racer if he or she goes near them. The final stretch takes place on a path similar to those at Bianco Hills, and if the player turns left into the square where the fountain is right before the finish line, they will find Item Boxes before a sharp turn back to the course. The award ceremony at the end of every cup in Double Dash!! is carried out here.
It is updated graphically in Mario Kart Wii. Hammer Bros., Toads, Goombas, and Shy Guys can be seen on the deck of The Sunshine cheering, and there are more umbrellas over the spectators on land. The biggest difference is that the pipe with the double items in Mario Kart: Double Dash!! is not present in Mario Kart Wii. Another difference is the boost ramp and item boxes in the area behind the colored crates at the end of the dock. The Cataquacks still appear, only the blue one wandering around the first tidal area was replaced with another green one.
 Track Layout
The racers first begin on the stoned straight road. After turning to the right of the first corner, the player can go to the left to find a ramp with Dash Panels and get an item box there. If the player takes an early left he will be shot out of a pipe and receive a double item box. However, this pipe does not appear in Mario Kart Wii. After jumping over the ramp, the racer lands on a small piece of land with a palm tree and grass surrounded by water. If the tide is high, the water will greatly slow down the vehicle crossing this zone. However, if the tide is low, the player can travel across without problems.
On the right path, Cataquacks appear roaming in the shore. They flip any vehicle in the air by contact and also take away some items on hand. While there is high tide, racers must follow the curved path, but by using a speed power-up, it is possible to take a shortcut over the water. During the low tide, racers can cut the path going straight to the next turn.
Racers then turn to the right below a pink natural arch where a set of item boxes lie in. After the arch, a pair of Cataquacks appear wandering another piece of the shore that leads to the right at the end.
After turning right, the beach ends in the cobbled road that leads straight to the starting line. Just before the line, there is another set of moving item boxes sliding left and right plus an alternate way to the left of the road that surrounds the fountain with a pair of item boxes behind. This way, however, is not a shortcut.
In Mario Kart Wii, two different tournaments took place on this course.
The first one required players to collect a total of 70 coins, which were scattered around the beach. It was the first tournament of July 2009, and it was later repeated as the first tournament of June 2011.
The second tournament required players to do a time trial race around a bunch of Mushroom Gorge mushrooms. That was the first tournament of April 2010. It was later repeated as the second tournament of October 2011, as well as being the first tournament of January 2013.
