Topography 
			
			In terms of surface area, Bavaria is the largest of Germany's 
			federal states, and also the southernmost. The landscape of Bavaria 
			can be subdivided into four major regions: the Alps, with the 
			Zugspitze, the highest mountain in Germany at 2,962m; the Alpine 
			foothills with their numerous lakes; the Eastern Bavarian central 
			mountains with the first ever national park in Germany; and the 
			Swabian-Franconian cuesta landscape. The longest rivers are the 
			Danube and the Main. Bavaria is also the most forested part of 
			Germany. 
			
			Bavaria was the first ever region in Europe to be precisely 
			measured.
			
			
			Nature conservation and environmental protection are of high 
			importance, and have been an integral part of the Bavarian 
			constitution since 1984. The German Alpine Association has set 
			itself the task of making the Alps accessible while preserving the 
			alpine environment. 
			
			The deepest borehole in Europe was drilled in Bavaria, for research 
			purposes. In Windischeschenbach, in the Upper Palatinate, the 
			continental deep-drilling reached a depth of 9,101 metres.
