Füssen in the context of Ostallgäu

The Lech (German pronunciation: [lɛç] ; Latin: Licus, Licca) is a river in Austria and Germany. It is a right tributary of the Danube 255 kilometres (158 mi) in length with a drainage basin of 3,919 square kilometres (1,513 sq mi). Its average discharge at the mouth is 115 m/s (4,100 cu ft/s).Its source is located in the Austrian state of Vorarlberg, where the river rises from lake Formarinsee in the Alps at an altitude of 1,870 metres (6,120 ft). It flows in a north-north-easterly direction and crosses the German border, forming the Lechfall, a 12-metre-high (39 ft) waterfall; afterwards the river enters a narrow gorge (the Lechschlucht). Leaving the Alps, it enters the plains of the Allgäu at Füssen at an elevation of 790 metres (2,580 ft) in the German state of Bavaria, where it used to be the location of the boundary with Swabia. The river runs through the city of Füssen and through the Forggensee, a man-made lake which is drained in winter. Here, it forms rapids and a waterfall.

The river flows further northwards through a region called the Lechrain, and passes the cities of Schongau, Landsberg, Augsburg (where it receives the Wertach) and Rain before entering the Danube just below Donauwörth at an elevation of 410 metres (1,330 ft). It is not navigable, owing to its torrential character and the gravel beds which choke its channel. There are extensive views of the Lech valley from Neuschwanstein Castle, near Füssen.

The Romantic Road (German: Romantische Straße, pronounced [ʁoˈmantɪʃə ˈʃtʁaːsə]) is a "theme route" devised by promotion-minded travel agents in the 1950s. It describes the 460 kilometres (290 miles) of surface roads between Würzburg and Füssen in southern Germany, specifically in Bavaria and Baden-Württemberg, linking a number of picturesque towns and castles. In medieval times, part of it was a trade route that connected the center of Germany with the south. Today, this region is thought by many international travellers to possess "quintessentially German" scenery and culture, in towns and cities such as Nördlingen, Dinkelsbühl and Rothenburg ob der Tauber and in castles such as Burg Harburg and the famous Neuschwanstein.

With about five million overnight stays, four to five times that number of day visits and around 15,000 jobs in tourism generated by the route, it is an economically important southern German travel destination.

The Forggensee, also called the Roßhaupten Reservoir, is a reservoir located north of Füssen in the county of Ostallgäu in Bavaria, Germany and one of many lakes in the region around Hohenschwangau and Neuschwanstein castles. With a surface area of 15.2 km, it is the fifth-largest lake in Bavaria and the largest reservoir in Germany by area. The River Lech flows through it. The Forggensee is known primarily as a tourist destination for aquatic sports and recreation. Besides Füssen, other settlements on the lake include Halblech, Rieden am Forggensee and Roßhaupten. The lake takes its name from the former hamlet of Forggen which has been submerged by the reservoir.

Schongau (German pronunciation: [ˈʃoːnɡaʊ] ) is a town in Bavaria, southern Germany, near the Alps. It is located along the Lech, between Landsberg am Lech and Füssen. It has about 12,000 inhabitants. Schongau has a well-preserved old wall around the center.

Neuschwanstein Castle (German: Schloss Neuschwanstein, pronounced [ˈʃlɔs nɔʏˈʃvaːnʃtaɪn]; Southern Bavarian: Schloss Neischwanstoa; lit. 'Newswanstone') is a 19th-century historicist palace on a rugged hill of the foothills of the Alps in the very south of Germany, near the border with Austria. It is located in the Swabia region of Bavaria, in the municipality of Schwangau, above the incorporated village of Hohenschwangau, which is also the location of Hohenschwangau Castle. The closest larger town is Füssen. The castle stands above the narrow gorge of the Pöllat stream, east of the Alpsee and Schwansee lakes, close to the mouth of the Lech into Lake Forggensee. Since 2025, the castle is part of the UNESCO World Heritage Site "The Palaces of King Ludwig II of Bavaria: Neuschwanstein, Linderhof, Schachen and Herrenchiemsee". According to Guinness World Records, at 65 metres (213 feet), it is the tallest castle in the world.

Despite the main residence of the Bavarian monarchs at the time—the Munich Residenz—being one of the most extensive palace complexes in the world, King Ludwig II of Bavaria felt the need to escape from the constraints he saw himself exposed to in Munich, and commissioned Neuschwanstein Castle on the remote northern edges of the Alps as a retreat but also in honour of composer Richard Wagner, whom he greatly admired. The three-winged complex was built between 1869 and 1892 based on plans by Eduard Riedel in the Neo-Romanesque style. Medieval knights' castles served as its architectural model. The throne room, the bedroom, and the minstrels' hall are particularly noteworthy.
