* The majority of the country is located on the North European Plain, which is characterized by its flatness.

* The Ardennes region in the southeast is the only mountainous area, with elevations reaching up to 694 meters (2,277 feet) at the Signal de Botrange, the highest point in Belgium.

* The rest of the country is mainly lowlands, with elevations ranging from 0 to 200 meters (656 feet).

So, while Belgium does have some hills and a mountainous region, it is predominantly known for its flat landscape.
