The lowest point in Aragon is on the Ebro river, close to Zaragoza, with an altitude of  high.

The three main geographical regions of Aragon are:
 The Aragonese Pyrenees has the highest points of this range that separates Spain from France. The main mountains are Aneto (3,404 m), the highest in the range, Posets Peak (3,375 m), Monte Perdido (3,355 m), Perdiguero (3,222 m), Cotiella (2,912 m), among others. The main Pyrenean valleys, formed by the rivers that are born there, are Ansó (Veral river), Hecho (Aragon Subordán river), Canfranc (Aragón river), Tena (Gállego river) and Broto-Ainsa-Benasque (Ara, Cinca and Ésera rivers). The Ordesa y Monte Perdido National Park lies above these valleys.
 Further south, the Ebro valley, irrigated by the Ebro river, is a rich and fertile agricultural area covered with vast fields of wheat, barley and other fruit and vegetable crops. Many beautiful and little-known settlements, castles and Roman ruins are found here.
 South of Zaragoza and the Ebro valley, the elevation rises again into the Sistema Ibérico, a complex system of mountain ranges that separates the Ebro valley from the Meseta Central and plains of Castile-La Mancha. The highest mountain in this range is the Moncayo with .

Rivers
Most of the Aragonese rivers are tributaries of the Ebro, Spain's largest river in volume and which divides Aragon into two. Some important tributaries on the left side of the river (rivers that come from the Pyrenees) are the Aragón, born in Huesca but flows into the community of Navarre, the Gállego and Cinca, which joins the Segre just before ending up in the Ebro. Right tributaries are the rivers Jalón, Huerva and Guadalupe.

On the Ebro, near the border with Catalonia, lies the Mequinenza Reservoir, with a length of about 110 km, and that is popularly known as the Sea of Aragon.

Climate

Climatically, Aragon can be divided into three areas:
 Continental Mediterranean. The Ebro valley. One of the severest climates in Spain and a daily and winter-summer temperature range. Low levels of rainfall which decrease as clouds move east towards Catalonia.
 Alpine-mountain climate. Short summers and very cold winters, though with big differences depending on altitude and orientation.
 Continental. The Calatayud-Daroca-Teruel region with mountains to the west and east that block the humid winds from the Atlantic Ocean and from the Mediterranean Sea. Low rainfall: . Hot summers and very cold winters.

In the middle of Aragon, which is only  above sea level, the annual average temperature is around . To the north and south of the Ebro valley, where the elevation rises to  above sea level, the temperature drops by two degrees. In the mountains, between , the temperatures are between .

Administrative divisions
Aragon consists of three provinces named after their capitals: Huesca, Teruel and Zaragoza. Each province is divided in comarcas (a comarca is a local administrative division) and these are divided in municipalities.

The most densely populated areas are around the valley of the Ebro river, particularly around Zaragoza, and in the Pyrenean foothills (the hills at the base of the Pyrenees), while the areas with the fewest inhabitants tend to be those that are higher up in the Pyrenean mountains, and in most of the southern province of Teruel.

The province of Zaragoza is the one with more inhabitants, with 978,638 people living there, representing % of the population of Aragon.
