After the new palace in town was built in the 16th century, the castle was abandoned and fell to ruins. According to its historical importance, however, it has been saved and partly reconstructed. Admission is free.
The hike up, starting from Neues Schloss (New Palace), is a mere 3 kms, but rather steep uphill. The walk took me about 45 minutes. Your reward will be an amazing view of Baden-Baden, the Northern Black Forest, and the Rhine plain over to Vosges and Palatine Forest.
See my travelogue page on Hohenbaden for more photos.
