The rivers Großache and Prien flow into the lake from the south, and the river Alz flows out towards the north. The Alz flows into the Inn which then merges with the Danube. The Chiemsee is divided into the bigger, north section, in the northeast, called Weitsee, and the Inselsee, in the southwest.

The Chiemgau, the region surrounding the Chiemsee, is a famous recreation area.
