DK Summit (also known as DK's Snowboard Cross in Japan and PAL regions) is the third race course of the Flower Cup in Mario Kart Wii. The track takes place on a snowy mountain which appears to be popular among Shy Guys.
The stage is somewhat a combination to DK Mountain from Mario Kart: Double Dash!! and DK Pass from Mario Kart DS. Like DK Mountain, it has a Barrel Cannon aimed at a mountain and a zigzagging, crevice-filled path to the goal line, and like DK Pass, it is covered in snow and has various small snowpiles that slow the player down if they run into them, as well as numerous Boost Pad ramps.
The race takes place in a mountain filled with snow and some skiing Shy Guys. This course introduces the half-pipe ramps in this game. There is a cannon that blasts the player to the top of the mountain. Later on, the player will have to descend from the summit, using ramps and bumpy hills to gain speed. After descending, the player will see Shy Guys snowboarding, which act like obstacles for the players, making any player who hits them spin out. After the half-pipe filled with Shy Guys, the player will soon end up back at the start of the course.
 Course layout
The racetrack starts near the base of the mountain, but quickly leads to a Barrel Cannon which fires racers to the summit. At the summit, the players will see half-pipe ramps for them to produce tricks on to gain speed. After the half-pipe area, there are two ramps to take; one has three folds in it while the other is one hill that has a boost panel on it; the triple-fold path allows players to perform more tricks, giving them mini turbos. Both ramps have item boxes lining the tip.
After the ramp is an area with thick snow containing pink stripes, with a pattern just like that of a candy cane's (which is scattered and counted offroad), and a lot of bumps following. The player can perform a multitude of tricks in this area, along with boosting on several with a boost panels on it. Several items boxes are located in this area, but only floating near the ramps with the boost panels on them. After this area, the player will drive through 1 U-turn to the right, while there is a half-pipe if the player doesn't turn right directly. The half-pipe contains 3 item boxes available for use if the player runs into them. After that, there is a turn left that leads into the area where there are Shy Guys skiing.
In the area where there are Shy Guys skiing, there are 2 half-pipe ramps on the sides. The player can drive straight, not using the half-pipe boosts, but the player may risk driving on the pink snow, which reduces the player's speed dramatically. The Shy Guys skiing can get in the way of the player, causing him or her to spin out with the same effect as Banana peels.
After that is a right angle turn to the right. After is the finish line and the start of another lap.
There are two shortcuts in this course. The first isn't technically a "shortcut", however, it is a faster alternative to clearing the first turn of the course, as mentioned in the Prima Guide for Mario Kart Wii. One can jump over the left side of the hill by using a ramp, where they can utilize a stunt. The second is shown after the player had passed the bumpy section of the course. There is a large chasm, and one may drift and boost across the chasm. They then can shave at least four seconds off his or her time.
The second December 2008 tournament took place on DK Summit. Players had to go through all 25 gates on the course. Nothing else had been changed on the course other than the added gates. This tournament was repeated as December 2010's second tournament, April 2012's first tournament, and June 2013's second tournament.
