Heidelberg sits on the Neckar River in Baden-Wuerttemberg, approximately 80 kilometres south of Frankfurt and 25 kilometres east of Mannheim. The city is home to Germany's oldest university, founded in 1386, and the combination of a baroque old town, ruined hillside castle, and a dramatic riverside setting has made it one of the country's most visited destinations. From Frankfurt Hauptbahnhof, ICE and IC trains reach Heidelberg Hauptbahnhof in under one hour, with frequent services running throughout the day. Note that Heidelberg Hauptbahnhof is located about 2 kilometres west of the old town — tram lines 21 and 24 connect the station to Bismarckplatz at the edge of the pedestrian zone. Heidelberg Schloss dominates the hillside above the old town and is one of the defining examples of romantic ruin architecture in Europe. Partially destroyed by French troops in the late 17th century and left in its current ruined state, the castle complex contains the German Apothecary Museum (Deutsches Apothekenmuseum) and the enormous Heidelberger Fass, a wine barrel with a capacity of 220,000 litres. A combined funicular and castle ticket costs around 9 EUR for adults and includes the Bergbahn ride from Kornmarkt in the old town, taking three minutes to reach the castle terrace. The castle grounds are open daily and offer broad views over the Neckar valley and the old town rooftops. From the castle, a descent through the vineyard paths and forest leads back to the old town in around 20 minutes and passes through areas not visible from the standard funicular route. The Alte Bruecke (Old Bridge), a baroque stone arch bridge dating to 1788, connects the old town to the Neuenheim bank of the Neckar. Crossing the bridge and climbing the Schlangenweg leads to the Philosophenweg, a 2-kilometre hillside path offering panoramic views across the castle and old town that historically served as a promenade for the university's academic community. Lunch is well served on Hauptstrasse, the old town's main pedestrian axis, and in the side streets parallel to it. Zum Roten Ochsen and Zum Seppl are two of the oldest student pubs, operating since the 18th century and serving traditional Palatinate and Swabian food.

Tips for visiting
- Take the Bergbahn funicular from Kornmarkt in the old town — a combined Bergbahn and castle ticket costs around 9 EUR and is the most efficient way up; do not board at the Hauptbahnhof stop by mistake.
- Walk back down from the castle through the vineyard and forest paths rather than returning by funicular — the descent takes around 20 minutes and reveals different angles of the ruins.
- Cross the Alte Bruecke to the Neuenheim side of the Neckar and climb the Schlangenweg to reach the Philosophenweg — the view across the old town and castle is the best in Heidelberg and is free.
- Hauptstrasse is very busy at summer weekends; Untere Strasse, the parallel lane one block south, has quieter local restaurants and fewer tourist crowds.
- Heidelberg Hauptbahnhof is 2 km west of the old town — take tram lines 21 or 24 to Bismarckplatz rather than walking the full distance, especially with luggage.
When to visit
Late April and May bring blooms to the castle gardens and are ideal for the Philosophenweg walk. Late September and October offer golden foliage on the hillside vineyards with fewer visitors than summer. Weekend summer afternoons on Hauptstrasse are very crowded; arriving before 10 am is advisable.
Frequently asked questions
How do I get to Heidelberg from Frankfurt?
ICE and IC trains from Frankfurt Hauptbahnhof to Heidelberg Hauptbahnhof run multiple times per hour and take 45-55 minutes. Regional trains also run on the same corridor but take longer. The DB Navigator app shows all connections with live timing.
How much does Heidelberg Castle cost to visit?
A combined ticket covering the Bergbahn funicular and castle entry costs around 9 EUR for adults. The castle courtyard can be entered without a ticket, but the interior rooms, the German Apothecary Museum, and the Heidelberger Fass wine barrel all require the paid admission.
What is the Philosophers Walk?
The Philosophenweg is a 2-kilometre hillside path on the northern bank of the Neckar, directly opposite the old town. It offers elevated views of the castle and old town and was historically a strolling route of Heidelberg University scholars. The path is reached by crossing the Alte Bruecke and climbing the Schlangenweg.
Is Heidelberg suitable as a half-day trip?
A half-day is sufficient to cover the castle, Alte Bruecke, and a walk through the old town pedestrian zone. A full day allows the Philosophenweg, the additional Bergbahn ride to the Koenigstuhl summit, and a leisurely lunch at one of the old student pubs on Hauptstrasse.
Is Heidelberg accessible for wheelchair users?
The old town pedestrian zone and Alte Bruecke are flat and accessible. The Bergbahn funicular to the castle is wheelchair accessible. The castle courtyard has uneven cobbled surfaces and the interior areas have limited ramp access. The Philosophenweg involves sustained hillside climbing and is not suitable for wheelchairs.
