The Bastei is the most famous natural landmark in Saxon Switzerland and one of the most visited spots in Germany east of Berlin. A cluster of sandstone rock pillars rises to 194 metres above the Elbe, connected by the 19th-century Bastei Bridge — a stone arch construction that threads between the towers and provides the landscape's defining view. The rocks were formed by the same geological process that shaped all of Saxon Switzerland: a vast sandstone plateau, laid down as a seabed 90 million years ago, then eroded over millennia by water into the towers, gorges, and table mountains of the present landscape.
The Bastei is about 20km from Pirna by road (take the B172 southeast along the Elbe, then turn up toward the village of Rathen). In summer, bus 253 runs from Pirna to Rathen, from where a short uphill walk reaches the viewpoint; alternatively the paddle-steamer stops at Rathen, with steps cut into the rock leading up from the landing stage. The site is heavily visited on summer weekends — arrive before 9am or after 4pm to have the rocks and the views to yourself. There is a café at the top with predictable quality and undeniable views.
