DK Summit (known as DK's Snowboard Cross in the PAL regions) is the third racecourse of the Flower Cup from Mario Kart Wii. The track takes place in a snowy mountain,. Players start in a part of the base of the mountain, being directly shot to the summit by a Barrel Cannon after the first curve. Once arrived in the summit, players go downhill, entering in a half-tunnel pass, where they can perform tricks and get Item Boxes in the air. Certain obstacles appear in the course, such as abysses located in the half-tunnel, and Shy Guys, who practice snowboarding before the finish line. The half-tunnel pass ends immediately in front of the finish line. The mountain's background features wooden buildings as well as two railways, where some Shy Guys sit.
The stage is heavily based on DK Mountain from Mario Kart: Double Dash!! and DK Pass from Mario Kart DS. Like DK Mountain, it has a shotting barrel aimed at a mountain and a sloppy way down to the goal line, and like DK Pass is it covered in snow and has various small snowpiles, that is around a rainbow-coloured pile that makes the players to jump.
