As the name suggests, it is a canyon filled level with a large number of rails which most of the level is spent grinding upon. This stage is quite long and for the majority of it, there is no solid ground. Completing this stage leads to Bullet Station.
Story
After defeating an army of robots in Robot Carnival, Team Sonic goes to destroy Eggman's base before sundown to meet their three-day deadline. Team Dark must find the entrance to Eggman's base to interrogate the Doctor. Team Rose must go beyond the rails to find Froggy and Chocola. Team Chaotix must infiltrate the terminal station as ordered by their client. Each team has a different reason to come here, but generally, they are looking to find and stop Dr. Eggman.

Trivia
This stage has used more rails than any other Sonic level. Final Rush from Sonic Adventure 2 is a close second.
During the Team Chaotix mission, if the player uses Leaf Swirl to go through the laser security, then switch to Charmy or Vector, it is possible to get to the teleport flower without activating the switches.
In Super Hard Mode, the rail boosters in this stage launch Team Sonic at an extremely fast speed on the rails which may make jumping to a parallel rail a bit trickier.
There are rock formations in this stage that resemble the Jack o' Lantern rock formations from the Pumpkin Hill stage in Sonic Adventure 2. There are also a few formations that resemble witches' hats.
