Ghost Valley 1
From the Super Mario Wiki
Appearance in Super Mario Kart
Ghost Valley 1 is the third course of the Mushroom Cup in Super Mario Kart. It is an old bridge surrounded by Boos. 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.
Appearance in 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.
