SNES Ghost Valley 1

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 returns as the third course of the Extra Mushroom Cup in Mario Kart: Super Circuit, and in Mario Kart Tour where it first appeared in the Halloween Tour. It is also the first ghost-related course in the Mario Kart series.

Layout
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 course. There are several jump pads on the track, the last one allowing drivers to cross a gap. Two other lines are placed directly before two Item Boxes which makes those only reachable by driving back or jumping over them with a Feather or a well-timed hop. There are some planks near the end that act as a shortcut, which can only be accessed with a Feather.

Mario Kart: Super Circuit
In Mario Kart: Super Circuit, Ghost Valley 1 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 holding the track up are removed.

Mario Kart Tour
Ghost Valley 1 reappears in Mario Kart Tour, being one of the few retro courses to not also appear in Mario Kart 7. It is also the only Super Mario Kart course in the game to have not previously appeared as a retro course since Mario Kart: Super Circuit along with Vanilla Lake 1. While the item boxes behind the two short jump pads are absent, an extra set of item boxes are added on the jump pad before them. The jump pad, gap, and 90° turn near the shortcut were moved back, and the straight following said turn is wider. The shortcut itself is blocked by a cutout of Boos, which hides a jump pad behind it. Additionally, the smoother turn at the end of the shortcut is wider. Unlike the original, guard edges aren't destroyed after bumping into them, and there are more present on the insides of the smoother 90° turns, the second of which was made sharp. This course is favored by Luigi, Pink Shy Guy, King Boo (Luigi's Mansion), and Rosalina (Halloween).

While many retro courses in Mario Kart Tour uses their original music arrangements, this course uses SNES Ghost Valley 2's music from Mario Kart Wii.
