By Train: The Fastest & Most Popular Choice
Taking the train is the quintessential German travel experience. You’ll depart from Frankfurt (Main) Hauptbahnhof and arrive at Heidelberg Hauptbahnhof.
- ICE (InterCity Express): These high-speed trains are the fastest option, getting you there in about 50-60 minutes. For the best prices, book your tickets in advance on the Deutsche Bahn (DB) website.
- Regional Trains (RE/RB): These are slower, taking around 90 minutes, but are much cheaper.
- Pro Tip: The Deutschland-Ticket (€49 Ticket) is a game-changer. This monthly pass covers all regional trains in Germany. If you’re planning other regional trips, it offers incredible value!
By Bus: The Most Budget-Friendly Option
For travelers keeping a close eye on their budget, the bus is a fantastic choice. Companies like Flixbus offer one-way fares starting as low as €7. The journey takes about 1.5 to 2 hours, but be aware that it can be affected by traffic. It’s a comfortable and easy way to save money for more schnitzel later!
By Car: The Most Flexible Journey
Driving offers the most freedom to set your own schedule. The route is a straightforward 85 km drive down the A5 Autobahn, taking about an hour without traffic. However, be warned: parking in Heidelberg’s Altstadt is extremely difficult and expensive. We strongly advise against it. Instead, aim for a parking garage on the edge of the Old Town like P12 (Kornmarkt) or P13 (Karlsplatz). Expect to pay around €20 for a full day of parking.
By Organized Tour: The Hassle-Free Day Trip
If you prefer to leave the planning to someone else, an organized tour from Frankfurt is a great all-inclusive option. These tours typically handle transportation and tickets, allowing you to simply sit back and enjoy the scenery.
Top 5 Unforgettable Things to Do in Heidelberg
Heidelberg’s charm lies in its collection of iconic landmarks, all nestled together. Here are the five must-see sights you can easily cover in a single day.
-
Explore the Majestic Heidelberg Castle (Schloss Heidelberg)
This is the star of the show! Perched on the hillside, the magnificent castle ruin is a breathtaking blend of Gothic and Renaissance styles. It’s the first thing you should do. To visit from Frankfurt, take the train to Heidelberg, then a bus to the Bergbahn (funicular) station at the Kornmarkt. Your castle ticket (€9 for adults in 2025) includes a round trip on the funicular, which whisks you up the hill.
- What to See: Wander the famous courtyard, marvel at the Großes Fass (Great Barrel)—an enormous 18th-century wine barrel—and take in the sweeping panoramic views from the terrace. Don’t miss the fascinating German Pharmacy Museum, also included with your ticket.
- Time Needed: Allow 2-3 hours to explore properly.
-
Walk Across the Karl Theodor Bridge (Alte Brücke)
After visiting the castle, head down to the iconic Old Bridge. This beautiful stone bridge with its nine arches offers one of the most stunning views of the castle. As you enter from the Old Town side, look for the famous Heidelberg Bridge Monkey statue. Legend has it that touching its mirror brings good fortune!
-
Wander Through the Altstadt (Old Town)
Heidelberg’s Altstadt famously escaped bombing in WWII, leaving its baroque charm perfectly intact. Get lost in the cobblestone streets and discover its key spots:
- Hauptstrasse: Stroll down one of Europe’s longest pedestrian-only streets, filled with shops and cafes.
- Marktplatz (Market Square): The heart of the Old Town, home to the impressive Church of the Holy Spirit.
- Kornmarkt: Arguably the prettiest square, offering a direct, stunning view up to the castle.
-
Get the Postcard View from the Philosophenweg (Philosopher’s Walk)
For the absolute best photo of Heidelberg, you need to cross the river. The Philosopher’s Walk is a famous path on the opposite hillside that provides the legendary “postcard view” of the castle, the Old Bridge, and the entire Altstadt. The climb is a bit steep, but the view is an unforgettable reward for your effort.
-
Uncover Secrets at the Studentenkarzer (Student Prison)
Don’t miss this quirky and fascinating piece of university history! From 1778 to 1914, unruly students were incarcerated in this “prison” for minor offenses like drinking too much. Instead of being grim, they spent their time covering the walls with incredible graffiti, poetry, and silhouettes, which you can still see today. It’s a quick, cheap (€4), and utterly unique stop.
