Heidelberg Walking Tours: Three Routes
Heidelberg is easy to explore on foot, and three self-guided routes cover the main sights without a booking. They differ a lot in effort, from a flat Old Town stroll to a long stair climb up the mountain.
Route one: Altstadt and riverside (easy, flat)
Start at Bismarckplatz and follow Hauptstrasse, the pedestrian street about 1.6 km long, east towards Marktplatz. Look at the Heiliggeistkirche and the Hercules Fountain, then turn north to the Alte Brücke and its gate. The bridge gives a good view of the castle. Continue across to the north bank for the view back at the Old Town. Allow about two hours with stops. The route is paved and suits pushchairs and wheelchairs.
Route two: Schlangenweg and Philosophenweg (steep, then moderate)
From the north end of the Old Bridge, climb the Schlangenweg, a series of cobbled switchbacks between vineyard walls. Cobbles are slippery in rain, fallen leaves and frost, so wear shoes with real grip. At the top, turn onto the Philosophenweg, a public path about 2 km long that follows the slope of the Heiligenberg and looks across to the castle. The Philosophengärtchen terrace has benches. Allow two to three hours including the climb, and walk in daylight.
Route three: castle to the Königstuhl (strenuous)
From Kornmarkt, walk up to the castle, or ride the funicular to save energy. From Molkenkur above the castle, the Himmelsleiter climbs roughly 1,200 rough sandstone steps to the Königstuhl summit. The steps vary in height and the path is steep and uneven, so only attempt it if you are fit, carry water and wear sturdy shoes. Ride the funicular back down. The upper section costs €10 return, or €7 one way.
Guided and themed walks
The night watchman walk Auf den Spuren der Nachtwächter starts at the Rathaus entrance on Marktplatz in the evening, usually around 20:00, lasts about 90 minutes and starts from about €16.90. Dates vary through the year, so confirm before you plan around it.
Sober stops on the way
The Studentenkarzer at Augustinergasse 2 shows cells covered in student graffiti. A combined ticket with the University Museum is €7.50, and the Karzer opens Monday to Saturday from 10:30 to 16:00 from October to May. On the Heiligenberg, the Thingstätte is an amphitheatre built in 1934 and 1935 under the Nazi regime. It is unlit and has uneven steps and no fences, so visit only in daylight and treat it as a historical site.
Practical notes
Heidelberg Hauptbahnhof is about 2 km west of the Old Town, so take a tram or bus to Bismarckplatz to start route one. The funicular has an annual maintenance shutdown early in the year, and the city has proposed closing it from early October 2027 to the end of March 2028.
