Shroom Ridge is a course in Mario Kart DS. It takes place on a cliffside somewhere in Mushroom Kingdom. It consists of many sharp turns, and during some of the track, your character is driving along the edge of the cliff, with no railing.
Other than other players and/or CPU's on the track, the biggest danger is all of the traffic driving on the road.

Shroom Ridge is a somewhat difficult course because of the cars, and the lack of guardrails protecting you from falling into the forest below. There are several sharp turns, making drifting key to victory. Karts with high handling, such as Dry Bomber are good for this.
