Undella Town is a coastal town known for its beaches. There is little of note here, except that it is the most well-connected location, featuring a total of five connections between other places. Opelucid City must be explored before the Marine Tube can be used.
To the north of west of Undella Town is Reversal Mountain. To the south is Route 14, while Route 13 is found to the north. To the east is Undella Bay, and the entrance to Marine Tube, a tunnel leading to Humilau City, is found within the town.
