The geograpical divison of Norway is defined by the dominant features of the landscape. In southern Norway, the major mountain massifs (including Hardangervidda, Jotunheimen and Dovre mountains) and the water divide (watershed) these create defines the major areas Western Fjords (Vestlandet), Trondelag (Trøndelag), and Eastern Valleys (Østlandet). Because these mountains are such a dominant feature, Norwegians often say "east of mountains", "west of mountains" or "north of mountains".

The big valleys of eastern Norway cuts into the central mountain massifs from east to west or from south to north, while the great fjords of the west similarly cuts into mountain massifs (or actullay the contigous mountain shield) from the shield's steep western edge to watershed. In most of Northern Norway the water divide defines the border with Sweden.The resulting "fragmented" landscape is clearly visible on maps and satelite images.

A very long and incredibly rugged coastline is Norway's most characteristic feature. The Geographical Survey of Norway esitmates that the coast (including islands) is more than 100,000 kilometer (only Canada has a longer coastline). The geographical survey also identifies 240,000 islands. Most Norwegians live within few kilometers from salt water (fjords or the ocean). Virtually all towns are sea ports, notable exceptions being towns on lake Mjøsa and the old mining towns Røros and Kongsberg.

Eastern Valleys are characterised by endless valleys, large lakes, dense pine forests, and in the eastern and southern corners relatively flat lowland. Alpine altitudes and vast mountain plateaus is found along the watershed (western and northern perimeter). Climate is mostly continental (cold winters, warm summers), except areas close to the Oslofjord. Oslo, the capital of Norway, is the main town in the eastern region. While Oslo is the geographical focus of eastern valleys, the two major valley/river systems terminate at Drammen and Fredrikstad.

Western Fjords are characterised by major fjords, countless islands, deep valleys ending abrubtly, steep hills, rivers often short and furious. Western fjords region is home to a number of the highest waterfalls in the world. Landscape is generally rugged and topography is complex or extremely complex. Climate is mostly mild/humid oceanic (no temperature extremes), but notably cooler winters and generally drier in the eastern/inner parts. Mountainous and large parts alpine altitudes, in the Sunnmøre region (south of Ålesund) and in Nordland county (particularly around Lofoten) the alpine mountains rise steeply from the Atlantic ocean. Bergen is the main town in this western fjords. Stavanger sits on the northern edge of Jæren, the only lowland plain in this area.

Trondelag landscape partly resembles that of eastern valleys, rolling pleasent landscapes, gentle lowland valleys, large rivers and lakes, partly highland, wide forests/bogs in several parts, weather-beaten low-lands on the coast, alpine mountains along the border. From coastal to continental climate. Ancient Trondheim is the main city in this area.

Northern Norway is the vast, varied area from Trondelag to the Russian and Finish border. Nordland and Troms counties are mostly extremely rugged (deep fjords, alpine mountains) like the Western Fjord region, but also include major inland valleys. Finnmark county is characterised by a vast plain/plateau of modest altitude cut through by wide fjords.

The South Coast (Sørlandet) is the lowland and related valleys/hills from the outer part of Oslofjord to  small town Flekkefjord. This area is characterised by small fjords, numerous small islands, numerous rivers, rolling hills/forests, modest altitudes. Kristiansand is the main city of this area.

There are several hundred thousand lakes in Norway (possible as much as 450,000) covering 5 % of the land (an area about the size of Slovenia).  More than 2,600 sq km or 1 % of the main land is covered by glaciers or permanent snow. 37 % of the main land is covered by forest, while 44 % is mountain or various types of treeless "open range".
