Circhester Stadium is located in the back end of town, past the Hero's Bath. It is the site at which the sixth installment in the Galarregion's Gym Challenge takes place.
In both games, during the Gym mission, the player is given a pair of dowsing rods, called Trap Detectors, and tasked with navigating a maze laden with hidden pitfalls. The dowsing rods will cause the player's choice of controller to rumble as they approach them, growing stronger the closer the player is to one; a visual indicator also appears on top of the rods to account for systems/settings that do not support rumble. If the player falls down a pit, they will return to the last solid platform they were on. This is further complicated in the final maze, where the player will need to navigate the maze while enduring a sandstormSw/blizzardSh that significantly obscures the player's vision. This weather is used only to disorient the player and does not have an effect on battles in the Challenge. After completing each maze the remaining pitfalls will reveal themselves, making backtracking easier if the player needs to go back to retreat or challenge a Trainer they missed.
