DS Shroom Ridge

Shroom Ridge is a racecourse only appearing in Mario Kart DS. The course takes place on a public road with traffic and runs on a mountain ridge, hence the name. For about half of the course, the right hand side has no railing and is a straight drop off the cliff. Shroom Ridge is also notable for the fact that in this course, the traffic moves in both directions, as opposed to the same direction as in most previous public road courses.

Layout
The race starts in a part of the road near to the cliff. Players go straight to encounter the first corner that turns to the left. The road becomes slighty wider and the racer leave the ridge going in between two hills. The road makes another abrupt turn to the right crossing the hills and then turns to the left. The road passes through an extense meadow with trees in the background behind one of the hills of the road that leads the racers uphill in a S turn that ends inside a tunnel traversing a hill bordering on the road. Racers run throughout the tunnel to make a slight turn to the left. The tunnel ends leading the racers again to the ridge. During the turn, the road tilts slightly downhill and then makes an S turn to the right. Racers must take now another turn to the left and lastly another to the right. The road ends in straight line towards the crossing line to complete the lap.

Trivia

 * A billboard can be seen on this course saying "Super Mario GP", which is a reference to the arcade Mario Kart series game Mario Kart Arcade GP.
 * Although completely coincidental, Shroom Ridge sounds similar to Mushridge, or rather its alternate name of "Mushroom Ridge". This town appeared in The Super Mario Bros. Super Show! episode "The Provolone Ranger".
 * The forested area below the cliff is similar to that in Mario Kart Wii, in the course of Moonview Highway.
 * On some of the trucks on Shroom Ridge there is an advertisement for Berries, and on other trucks there are ads for "Fresh "Cheep Cheep".
