Albania has a total area of 28,750 square kilometers. Its coastline is 362 kilometres long and extends along the Adriatic and Ionian Seas. The lowlands of the west face the Adriatic Sea. The 70% of the country that is mountainous is rugged and often inaccessible from the outside. The highest mountain is Korab situated in the district of Dibra, reaching up to 2,753 metres (9,032 ft). The country has a continental climate at its high altitude regions with cold winters and hot summers. Besides the capital city of Tirana, which has 800,000 inhabitants, the principal cities are Durrës, Elbasan, Shkodër, Gjirokastër, Vlorë, Korçë and Kukës. In Albanian grammar, a word can have indefinite and definite forms, and this also applies to city names: both Tiranë and Tirana, Shkodër and Shkodra are used.

The three largest and deepest tectonic lakes of the Balkan Peninsula are located in Albania. Lake Shkodër in the country's northwest has a surface of 368 km², out of which 149 km² belong to Albania. The Albanian shoreline of the lake is 57 km. Ohrid Lake is situated in the country's southeast and is shared between Albania and Republic of Macedonia. It has a maximal depth of 289 meters and a variety of unique flora and fauna can be found there, including “living fossils” and many endemic species. Because of its natural and historical value, Ohrid Lake is under the protection of UNESCO.

Over a third of the territory of Albania – about 10,000 square kilometres (2.5 million acres) – is forested and the country was very rich in flora. About 3.000 different species of plants grow in Albania, many of which are used for medicinal purposes. Phytogeographically, Albania belongs to the Boreal Kingdom and is shared between the Adriatic and East Mediterranean provinces of the Mediterranean Region and the Illyrian province of the Circumboreal Region. According to the WWF and Digital Map of European Ecological Regions by the European Environment Agency, the territory of Albania can be subdivided into three ecoregions: the Illyrian deciduous forests, Pindus Mountains mixed forests and Dinaric Mountains mixed forests. The forests are home to a wide range of mammals, including wolves, bears, wild boars, and chamois. Lynx, wildcats, pine martens and polecats are rare, but survive in some parts of the country.
