DK Summit (also known as DK's Snowboard Cross in Europe and Australia) is a course in Mario Kart Wii. It is the third course in the Flower Cup and also the seventh track in the entire game. It takes place in a snowboarding mountain, including some other skiers, deep snow, and slopes you can get your items from.

After starting the race and turning right straight into some gates succeeded by a cannon, land on a high slope and turn left you begin journey down the cliff. Jump off of a ramp or travel through some bumps, but watch out for the deep snow. Then, maneuver through some bumps, some speed boosts scattered in them will help you out. Travel around two tough slopes and grab an item while you're at it. After you finish, jump over some deep snow patches or use mushrooms to pass through them. Turn right and finish the lap.
DK Summit makes a striking resemblance to the track called DK Pass, which is found in Mario Kart DS, again being a track covered in snow.
