How many days in Heidelberg? 3 days for the castle, the old town and the Neckar valley
By Tony Panopoulos · travel-agency planner in Greece · Updated
Heidelberg is a university town squeezed between the Neckar river and wooded hills, with a ruined red sandstone castle above the roofs. The old town is a single long strip, so it is easy to see in a day, which is what most coach tours do. Give it three days: one for the castle and the riverbanks, one for the university and the hills, and one up the Neckar valley or to the palaces and cathedrals of the Rhine plain.
Short answer
Two days covers the castle, the Old Bridge, the Philosophers' Walk and the old town. Three lets you add Königstuhl and a boat or day trip without rushing the castle.
The 3-day plan, day by day
Day 1: Heidelberg Castle and the Old Bridge
Morning. Take the Bergbahn funicular from the Kornmarkt station (a few minutes) up to Heidelberg Castle. The combined ticket (roughly €9-11; check current price) covers the funicular, the courtyard, the Great Tun, a wine barrel holding about 220,000 litres, and the German Pharmacy Museum. Arrive at opening, about 9:00, before tour groups.
Afternoon. Walk the castle gardens and terraces for the view over the old town, then walk down the stepped lanes to Kornmarkt and the Marktplatz with the Gothic Church of the Holy Spirit (Heiliggeistkirche). Climb its tower for a small fee if it is open.
Evening. Cross the Old Bridge (Alte Brücke) through its twin-towered gate; touch the bronze bridge monkey on the town side for luck. Dinner in the old town at a traditional student tavern costs about €18-28 for a main and a beer.
On three Saturday evenings each summer (usually in June, July and September), the castle illumination lights the ruins red with fireworks over the river. Hotels fill early on those dates.
Day 2: The Philosophers' Walk, the university and Hauptstraße
Morning. From the Old Bridge, climb the steep Schlangenweg (Snake Path, about 15 minutes) to the Philosophenweg on the north bank, a flat path through gardens with the classic view of the castle and the old town. Continue up to the Heiligenberg for the ruins of a monastery and the Thingstätte, a 1930s open-air amphitheatre (about 45 minutes more).
Afternoon. Back in town, visit the Student Prison (Studentenkarzer), where students were locked up for misbehaviour until 1914 and covered the walls with graffiti; the ticket (about €4-6) usually includes the University Museum in the Old University. Then walk Hauptstraße, the pedestrian street of about 1.6 km from Bismarckplatz to Karlstor.
Evening. Buy a Studentenkuss (Student's Kiss) chocolate at the old café where it was created, then have dinner in the Untere Straße, a lane of bars and pubs parallel to Hauptstraße, lively with students until late.
The Philosophers' Walk faces south and is in full sun in the afternoon. Walk it in the morning for softer light on the castle and cooler air.
Day 3: Königstuhl and the Neckar valley
Morning. Ride the funicular past the castle and change to the historic upper section to the Königstuhl, at about 568 metres, for the view over the Rhine plain on a clear day. Walk back down through the forest in about 1-1.5 hours, or ride down.
Afternoon. Take a Neckar boat trip from the landing near the Old Bridge upstream to Neckarsteinach, a village with four castles on its hillside (about 1.5 hours each way, roughly €18-25 return; boats run mainly from April to October). Return by boat or by the S-Bahn in about 20 minutes.
Evening. Have a riverside dinner in Neuenheim, the residential district across the Theodor Heuss bridge, with beer gardens on the bank, or try a Flammkuchen and a glass of local wine in the old town (about €12-18).
Instead of the boat, a half-day by train or car to the baroque Schwetzingen palace gardens (about 20 minutes) or the Romanesque cathedral of Speyer (about 30-45 minutes) works well in spring and autumn.
Only have 2 days?
With 2 days, do Day 1 as written and combine the Philosophers' Walk with the Student Prison and Hauptstraße on Day 2. You lose Königstuhl and the boat trip.
Got extra days?
A 4th day can go to Speyer and its cathedral, to Worms on the Rhine, or by train to Frankfurt (about 1 hour) or Strasbourg (about 1.5-2 hours via Karlsruhe or Mannheim).

Getting around
The old town is walkable: Bismarckplatz to the Karlstor along Hauptstraße is about 25 minutes. Trams and buses of the regional VRN network link the main station, Bismarckplatz and the old town; a single is about €2-3 and a day ticket about €7-10 (check current fares). From Frankfurt Airport, shuttle buses and trains take about 1 hour. Mannheim has fast ICE trains and is 10-15 minutes by S-Bahn. Parking in the old town is limited and expensive; leave the car in a garage.
What to eat in Heidelberg
Heidelberg's student taverns serve hearty Baden and Palatinate food: schnitzel, Maultaschen (filled pasta squares), Flammkuchen (thin tart with cream, onions and bacon) and, from the Palatinate, Saumagen, a stuffed pork stomach. A main costs about €14-24. The surrounding hills grow Riesling and Pinot noir (Spätburgunder); a glass is about €5-8. In spring, look for white asparagus (Spargel) from the Rhine plain, usually April to June. Bakeries sell pretzels for about €1-1.50.
Best time to visit
May to June and September to October, with highs of 18-26°C and the castle gardens green. July and August are warm, up to 30°C, and busiest with tour groups. December brings Christmas markets across several squares of the old town, with mulled wine and cold, often grey weather around 2-6°C.

Before you go
Common questions
Is one day in Heidelberg enough?
One day covers the castle, the Old Bridge and a walk down Hauptstraße, which is what most day trips from Frankfurt do. You will miss the Philosophers' Walk at its best time, the Student Prison, Königstuhl and the river. Two nights gives a much calmer visit and lets you enjoy the town in the evening, after the coaches leave.
Do I need to book the castle in advance?
Usually not. Tickets are sold at the funicular station and at the castle, and include the courtyard, the Great Tun and the Pharmacy Museum. Guided tours of the interiors cost extra and run at set times. On illumination nights and summer weekends, arrive early or buy online to skip the funicular queue.
Can I walk up to the castle?
Yes. From the Kornmarkt, steep stepped lanes and the path called the Burgweg reach the castle in about 15-20 minutes. Walking is free, but you still need a ticket for the courtyard and the Great Tun. Many people walk up and take the funicular down, or the other way round.
Is Heidelberg good as a base?
Yes, for this part of Germany. Trains link it to Mannheim, Frankfurt, Karlsruhe and Stuttgart, and day trips go to Speyer, Worms, Schwetzingen and the Neckar valley castles. Hotels in the old town are pricier than in the station area, but the walk to the sights is short, and evenings in the old lanes are the point.
