10 Best Things to Do in Heidelberg
Heidelberg’s best sights cluster into two easy days, most of them within a 15-minute walk of the Kornmarkt funicular station. Ride up to the ruined castle first, walk the Altstadt’s pedestrian spine second, then cross the river for the Philosophenweg’s postcard view. Check current hours and prices at schloss-heidelberg.de before you go, they shift year to year.

1. Heidelberg Castle
Start here, and start with the right frame: this is a ruin, not a restored palace. French troops blew up the towers and walls in 1689 and 1693 during the War of the Palatinate Succession, and the Ottheinrichsbau facade, the Renaissance showpiece, was struck by lightning in 1764 after already losing its roof to fire in 1693. The Großes Fass (Great Tun) in the cellars is an enormous 1751 wine barrel, and the German Pharmacy Museum covers centuries of medical history in the Apothecary Tower. Take the Bergbahn funicular up from the Kornmarkt, or walk the Kurzer Buckel footpath in 10-15 minutes. There’s no UNESCO status here, that belongs to Speyer’s cathedral, a day trip away.
2. The Altstadt and Hauptstrasse
Heidelberg’s old town is one of Germany’s largest car-free zones, centered on the Hauptstrasse, a pedestrianized street just over a mile long. Walk it end to end and you’ll cross the Marktplatz, home to the late-Gothic Heiliggeistkirche, and the Kornmarkt, where the funicular departs.
3. Philosophenweg
Cross the Neckar to the north bank and climb the Philosophenweg, walked by university scholars since around 1788. This delivers the classic view: castle, red rooftops, and the Old Bridge together, best around sunset.
4. The Old Bridge and Brückenaffe
The Alte Brücke dates to 1786-88; earlier versions on the same site were destroyed by floods and the 1689 French campaign. At its north gate, the bronze Brückenaffe (Bridge Monkey) continues a tradition documented since 1481, though the current statue was cast in 1979.
5. Heidelberg University and the Studentenkarzer
Founded in 1386, this is Germany’s oldest university. Behind the Old University, the Studentenkarzer (student prison) held misbehaving students from the 1780s until 1914, and its walls are still covered in the graffiti they left behind.
6. A Neckar boat cruise
Weisse Flotte Heidelberg runs everything from a 50-minute panorama loop past the castle to a roughly 3-hour round trip to Neckarsteinach’s four-castle skyline. Season runs Easter to late October.
7. The Heiligenberg
Across the river and above the Philosophenweg, the Heiligenberg carries St. Michael’s Monastery ruins (founded around 870) and the Thingstätte, a Nazi-era open-air amphitheatre built in 1935 for propaganda rallies. It’s a real, publicly accessible site worth understanding in context, not a scenic curiosity to breeze past.
8. The Königstuhl summit
Ride the historic upper section of the Bergbahn to the Königstuhl (about 568m), with views over the Neckar valley toward the Rhine lowlands on a clear day.
9. Marktplatz after dark
The square empties of day-trip crowds by evening, when the Heiliggeistkirche and the surrounding facades are lit and the outdoor tables fill with a more local mix of students and residents.
What’s the one thing first-timers get wrong about the castle?
Expecting an intact palace. The castle’s identity is the ruin itself, deliberately left unrestored since the Romantic era. Budget your visit around that, not around a “grand interior tour” that doesn’t exist in the way it does at, say, Neuschwanstein.
Plan the rest of your trip
For the day-by-day version, see the 3-day itinerary . For food specifics, see best places to eat , and for the full overview, start at the main Heidelberg guide .
One concrete tip: do the castle first thing in the morning if you’re visiting June through August. The Bergbahn queue at Kornmarkt gets long by midday in peak season, and the ruin photographs better in soft early light anyway.
