Germany's outdoor infrastructure is the best-organised in Europe and its landscapes are more varied than international perception suggests. The Berchtesgaden National Park in Bavaria — the only alpine national park in Germany — delivers Königssee (a fjord-like lake accessible only by electric boat) and the Watzmann ridge walk above 2,700 metres, with views over Austria. The Rhine Gorge between Koblenz and Bingen (UNESCO World Heritage) is Germany's most-walked long-distance trail — 125 kilometres of vineyard, castle, and river above the Rheingold landscape. The Saxon Switzerland National Park around the Elbe sandstone mountains carries the Bastei bridge above eroded rock pillars in a landscape that is instantly recognisable from Caspar David Friedrich's paintings. The Wadden Sea National Parks across three federal states are part of the same UNESCO tidal flat system as the Dutch and Danish coasts. Tours by locals often reveal the rhythm of the place in a more natural way. The hidden gems usually do the rest.
