It's an easy day trip to see the Burg Hohenzollern, a fairytale castle dramatically set on top of a conical hill.
Hohenzollern Castle is the ancestral seat of the formerly imperial House of Hohenzollern. The third of three hilltop castles built on the site, it is located atop Mount Hohenzollern, above and south of Hechingen, on the edge of the Swabian Jura in central Baden-Württemberg, Germany. The name derives from Söller (terrace), from the Latin solarium.

Laboratory dedicated to the cradles of biochemistry and housed in the old walls of Schloss Hohentübingen, in its close proximity to the Ancient Culture Museum.
The Schloss, or castle, can be a fun place to wander around. Look at the intricately carved gate at the entrance. Skip most of the centre courtyard and head up the stairs on the back side of the courtyard. This leads to a beautiful garden/courtyard, with some beautiful views from atop the wall to the left. Alternatively, go through the tunnel on the backside of the main courtyard that will take you through the backside of the castle, a much more medieval and beautiful part of the Schloss. At certain times, there are archers shooting in the eastern moat (the "Hasengraben") of the castle. From back here there is a path that will take you along the wall of the castle and through the woods, ending up on Haaggasse very near the Marktplatz.

The river Neckar next to the city centre, on which the students go punting (similar to what they do in Oxford or Cambridge in summer time, occasionally with a barbecue and a crate of beer on board.
The old city centre full of crooked half-timbered houses, small alleys, cobblestone roadwork and some nice old churches.
