Lucerne is located at the outfall of Lake Lucerne into the river Reuss, which flows from south-east to north-west. The city occupies both banks of the river and the lowest reach of the lake, with the city centre straddling the river immediately downstream of the outfall. The city's suburbs climb the hills to the north-east and south-west, and stretch out along the river and lake banks, whilst the recently added area of Littau is to the north-west.
