Red sandstone castle ruins on a wooded hill, an old stone bridge across the Neckar, and Germany’s oldest university filling the lanes with students. Heidelberg is the romantic Germany of old paintings, and it really does look like that. Here’s how we’d spend our time.
Short answer: One full day covers the castle (take the funicular up), the old town, the Old Bridge and the Philosophers’ Walk. Stay a second day for the Königstuhl, the Student Prison and a trip to Schwetzingen or Speyer. From Frankfurt it’s under an hour by the fastest trains.
Heidelberg University was founded in 1386, which makes it the oldest in Germany, and the town has been a favorite of poets and painters since the Romantic era. The castle was destroyed in wars in the 17th century and partly by lightning later on, and its ruins became one of the most famous sights in Germany.
My tip: go up to the castle in the morning, then cross the Old Bridge in the afternoon and climb the Philosophers’ Walk for the view back at the castle in the evening light.

The great red sandstone ruin above the town, with the Renaissance facades of the Ottheinrich and Friedrich buildings, the Great Barrel (one of the largest wine barrels in the world) and the German Pharmacy Museum.
Good to know: the ticket includes the funicular up and down, the castle courtyard, the Great Barrel and the Pharmacy Museum. Courtyard daily 9:00 to 18:00 (last entry 17:30). The interiors are only open on guided tours.
The stone bridge from the 1780s with its white gate towers. On the old-town side, look for the bronze bridge monkey holding a mirror; touching it is said to bring you back to Heidelberg.
Good to know: the bridge is busy at midday. Early morning and evening are much calmer.
A path on the hillside across the river, with the best view of the castle, the old town and the bridge. It’s a steep climb up the Schlangenweg, but worth it.
Good to know: cross the Old Bridge and follow the signs for the Schlangenweg. Allow about an hour for the round trip.
Until 1914, misbehaving students were locked up here, and they covered the walls with graffiti, drawings and silhouettes. One of the quirkiest sights in Germany.
Good to know: in winter Monday to Saturday 10:30 to 16:00. The combo ticket includes the University Museum in the Old University.
The market square with the Church of the Holy Spirit, and the long pedestrian Hauptstraße running through the old town. In Advent, the Christmas market fills this square and five others.
Good to know: the Hauptstraße is more than a kilometer long, so walk it one way and take the bus back if your feet are tired.
Keep riding the funicular past the castle and Molkenkur up to the Königstuhl hilltop for wide views over the Rhine plain. The upper line uses historic cars.
Good to know: the Königstuhl ticket for the upper line is €10 return in 2026 (prices rise on 1 January 2027).
Choose how long you have (or who’s coming) and get a ready-made plan. Save the one you like to your trip list.

About 20 minutes by S-Bahn (then a 10-minute walk) or a direct bus. Huge baroque gardens with a mosque and Roman temple follies.
