SNES Ghost Valley 1

Ghost Valley 1 is the third course of the Mushroom Cup in Super Mario Kart, later reused as the third course of the Extra Mushroom Cup in Mario Kart: Super Circuit. It is an old bridge surrounded by Boos.

Super Mario Kart
The course has limited guard edges, but bumping into a tile at the edge of the bridge will destroy it, allowing players to go through and fall off the stage. There are several jump lines on the track, the last one allowing the driver to cross a gap. Two other lines are placed directly before two Item Boxes which makes those only reachable by driving back or avoiding the jump lines with a Cape Feather. There are some planks near the end that act as a shortcut. There are no guard edges. This area can only be accessed using a Cape Feather.

Mario Kart: Super Circuit
Ghost Valley 1 is the third track in the Extra Mushroom Cup. It uses the background from Boo Lake. It is pretty much the same as its SNES counterpart, although the two small bouncy pads before the two lone item boxes and the legs to hold the track up are removed. Despite that, the shortcut returns, despite a lack of Cape Feathers.

Trivia

 * The music for Ghost Valley (and subsequent Ghost Valley courses) sounds very similar to the music used for the Ghost House levels from Super Mario World.
 * Part of the music played here (and subsequent Ghost Valley courses) was remixed and played on the course Banshee Boardwalk in Mario Kart 64.
