Located below the Great Hall, Cavern Hole is accessible through a set of stairs. Cavern Hole can also be reached from the wine cellar through a small corridor and a sloping ramp. An archway marks the entry between Cavern Hole and the Kitchen.
Not as decorated as the Great Hall, Cavern Hole has large slit windows and a stone floor. It is furnished with a large table and is lit by candles in sconces.
Redwallers usually eat their informal meals, especially breakfast and supper, in this room. It is occasionally used as a meeting place in times of crisis in place of the Great Hall.
