There are three main geographical regions to Belgium: the coastal plain, the central plateau, and the Ardennes uplands.
The coastal area is a series of sandy beaches and polders, backed by protecting dunes.
Inland, up to the Meuse River, the land is generally flat, with numerous canals and dikes protecting the land from the sea. It's criss-crossed by many small tributaries of the Schelde River. Valley's, caves and small gorges can also be found in this area.
East of the Meuse, forested hilly conditions rise to the rugged and flat-topped mountains of the Ardennes Region. The highest point is the Botrange, at 2,276 ft. (694m).
