The pale mist rises from the Neckar River at dawn, the red sandstone of Heidelberg Castle glowing through the haze, the first chime of the Heiliggeistkirche bells echoing through the narrow streets. The sandstone, the red, the warm, the 500 years old, a block at the Heidelberg Castle, the 13th to 17th century fortress that is the most famous castle ruin in Germany. Three million visitors come each year. This is the castle that inspired the Romantic movement: Turner painted it, Hugo wrote about it, Goethe walked its grounds, and millions of tourists have followed since the 19th century. The sandstone glows deep orange at sunset on a May evening, the last light catching the red stone and the Neckar River silver below, couples on the Scheffelterrasse sharing a bottle of Riesling, students from the oldest university in Germany, founded in 1386, singing “Gaudeamus Igitur” at the next table. Here is your day-trip guide to Heidelberg.

The Castle and the Great Tun

Walk up the steep cobbled Burgweg, 15 minutes from the Kornmarkt. The walk is free and beautiful, and the exercise earns the Riesling at the top. You can skip the 9-euro funicular. The castle entry costs 9 euros for the courtyard and the German Apothecary Museum. The Heidelberg Card at 16 euros for 2 days includes castle, funicular, and public transport, worth it for a day visit. The Great Tun, built in 1751, is the largest wine barrel in the world with a capacity of 221,726 litres, 7 metres wide, and 8.5 metres deep, with a dance floor on top. Perkeo, the court dwarf and legendary drinker who guarded the previous barrel and supposedly died when he accidentally drank water, has his statue watching over the barrel. The ruined Friedrichsbau, the Renaissance building, has the most beautiful facade at the castle with statues of Wittelsbach rulers lining the front. The view from the Scheffelterrasse takes in the Old Town, the Old Bridge built in 1788, the Neckar, and the Philosophers’ Way on the opposite hill. This is the best castle view in Germany.

The Old Town and the Hauptstrasse

From the castle, walk through the Kornmarkt to the Hauptstrasse, the longest pedestrian shopping street in Europe at 1.6 kilometres, lined with 17th-century buildings rebuilt after the French destruction of 1693. The essential stop is Studentenkus, the Student Kiss chocolate shop at number 110, established in 1863. Chaperoned university students were not allowed to kiss publicly, so young men gave these chocolates to the Fräuleins instead. Each chocolate costs 1.50 euros and they are the essential Heidelberg souvenir. The Heiliggeistkirche, the Church of the Holy Spirit, is a 14th-century Gothic church built from red sandstone and the most beautiful church in Heidelberg. climb the tower for 3 euros and 208 steps for the best view of the Old Town from inside. The Universitatsplatz, the university square, is dominated by the Alte Universitat, the Old University, built in 1712, and the Studentenkarzer, the student prison where misbehaving students were confined between 1778 and 1914. The walls inside are covered in graffiti left by the imprisoned students, a fascinating glimpse into student life in the 19th century.

The Old Bridge and the Monkey

Walk the Old Bridge, the Karl-Theodor-Brucke built in 1788, at sunset. It costs nothing and offers the classic view of the castle and the Neckar. The bronze monkey at the city gate is a 1979 replica of a 15th-century original. The tradition says to touch the mirror for wealth, the mice for fertility, and the fingers to return to Heidelberg. The bridge gate, the Bruckentor, was originally part of the city fortifications and is topped with a helmeted spire that frames the castle perfectly in photographs. The bridge itself is 200 metres long and built from Neckar Valley sandstone.

The Philosophers’ Way

The Philosophenweg, the Philosophers’ Way, is the essential Heidelberg walk. Walk up from the Old Bridge via the Schlangenweg, the Snake Path, a 20-minute steep climb of 191 metres, then follow the flat path at the top for 2 kilometres along the hillside through vineyards and exotic plants. The microclimate of the sheltered Neckar valley allows palms, citrus, and bamboo to grow here. The view from the path takes in the Old Town, the Castle, and the Neckar, the best view in Heidelberg at sunset. Bring a bottle of Riesling and glasses, because the Philosophenweg at sunset is the essential romantic Heidelberg experience. The path is named for the professors and philosophers of the university who walked here to think, including Hegel and Schelling in the early 19th century.

Heidelberg Beyond the Day Trip

If you have time beyond the classic sights, the Konigstuhl, the King’s Seat, is the 568-metre mountain that towers above the castle. The funicular to the top is included in the Heidelberg Card and the view from the summit stretches across the Rhine valley. The Heidelberg Zoo, one of the oldest in Germany founded in 1933, houses 1,200 animals. The Thingstatte, an open-air amphitheatre built by the Nazis in 1935 on the Heiligenberg, is a sobering reminder of the city’s 20th-century history, though it now hosts concerts and theatre performances. The Altstadt, the Old Town, has over 20 wine taverns and student pubs where a glass of local Riesling costs 4 to 5 euros and a main meal costs 10 to 15 euros. The city is compact enough to see the main sights in one day but rewarding enough to deserve a weekend.
