The Bastei is a rock formation with a viewing platform in Saxon Switzerland on the right bank of the Elbe River between the spa town of Rathen and Stadt Wehlen. It is one of the most visited tourist attractions in Saxon Switzerland. From the Bastei, the narrow rocky reef drops steeply over 194 meters into the Elbe. It offers a wide view into the Elbe valley and over the Elbe Sandstone Mountains. On the plateau behind the Bastei is a hotel with restaurant.
