Heidelberg, Germany: A City I Love to Wander

Castle ruins, a mile-long shopping street, graceful riverside villas and a youthful student spirit. Heidelberg is one of those places I don’t just admire — I genuinely enjoy being in.

Heidelberg is a city I love to walk

There are cities I admire for their monuments and cities I enjoy because of how they make me feel. Heidelberg belongs firmly in the second category — though it has more than enough monuments to keep the guidebooks happy. I find real pleasure in simply walking its streets. There’s a warmth to the place: old stone, lively cafés, students hurrying to lectures and the castle keeping a watchful eye over everything. It’s a city with history in its bones and youth in its step.

Mark Twain got here before me

I am in excellent company when it comes to falling for Heidelberg. Mark Twain spent more than three months here in 1878, and his observations appeared in A Tramp Abroad in 1880. He was fascinated by the town, the castle, the students and the German language — a subject on which he was gloriously mischievous. He described impressing a castle attendant with his German, only to be told that it was so unusual it might deserve a place in the museum. I rather like that. Any traveller who has confidently ordered something in a foreign language and received a baffled look will understand the joke. Heidelberg’s Mark Twain Center tells more of his stay.

An old town that refuses to grow old

Heidelberg’s Altstadt is full of the sort of buildings that make me slow my pace and look up. The façades, little side streets, church towers and market squares feel wonderfully historic. Yet this is no museum town where everybody whispers and tiptoes. Heidelberg University was founded in 1386, and the students give the city a youthful, cheerful energy. You can be standing beside a centuries-old building while a group of young people are discussing tomorrow’s exam or tonight’s plans. That mixture of old and new is part of the magic.

The Hauptstraße: a mile of happy distractions

And then there’s the Hauptstraße, Heidelberg’s long pedestrian shopping street, stretching for roughly 1.6 kilometres — about a mile through the Old Town. I love strolling along it without a strict agenda. There are familiar shops, independent boutiques, bookshops, bakeries, cafés and tempting little detours into side lanes. You can do some serious shopping if you wish. Personally, I think the greater pleasure is in wandering, looking into windows, watching people and finding somewhere to sit with a coffee. A shopping street that doubles as a history lesson — not a bad arrangement.

Across the Neckar: villas and a different Heidelberg

Cross the Old Bridge and turn back to admire the castle and the rooftops. On the opposite bank, especially around Neuenheim, you’ll notice handsome villas and leafy residential streets. I always find myself imagining what it might be like to live in one of those elegant homes with the river and Old Town nearby. Of course, my imagination is considerably more generous than my property budget. It’s worth crossing the river not just for the famous view, but to enjoy this quieter, gracious side of the city.

The Philosopher's Walk and Heidelberg's sunny disposition

Above the northern bank runs the Philosophenweg — the Philosopher’s Walk. The outlook over the river, bridge, Old Town and castle is magnificent. This sunny slope has a remarkably mild microclimate; plants such as figs, cypresses and even more Mediterranean-looking species can thrive here. Heidelberg is in one of Germany’s warmer regions, and that adds to its easygoing atmosphere. I wouldn’t promise you eternal sunshine — German weather has a sense of humour of its own — but when the sun comes out, Heidelberg knows how to make the most of it. Be warned: reaching the higher path involves a steep climb.

The castle: splendid even in ruins

Heidelberg Castle is not the neat, perfectly restored palace you might expect. It is partly ruined, gloriously romantic and all the more atmospheric for it. The red sandstone walls rise above the Old Town, and the views across the Neckar valley are memorable. The castle also houses the famous giant wine barrel, which seems entirely appropriate for a region that takes its wine seriously. You can reach the castle area by the hillside railway, although ticketing and access should be checked before you go. I think the castle is at its best when you allow yourself time to enjoy the setting, not just photograph the walls.

A city with serious history and a light touch

Heidelberg’s story reaches back centuries. Its university helped establish it as a centre of scholarship, while the castle and the Palatine electors placed it in the middle of European political and religious struggles. The Old Town’s Baroque appearance owes much to rebuilding after destruction in the late seventeenth century. Much of Heidelberg escaped the devastation that hit so many German cities during the Second World War. But the thing I enjoy is that all this history coexists with ordinary life. Nobody needs to wear a powdered wig to buy a sandwich.

My favourite kind of Heidelberg afternoon

If I were planning a relaxed visit, I’d start by wandering the Hauptstraße, turn into the Marktplatz, admire the Church of the Holy Spirit and follow whichever side street caught my eye. Then I’d walk down to the Old Bridge and cross the Neckar for the view. With more time and energy, I’d explore the Philosopher’s Walk or visit the castle. Somewhere along the way there would be coffee, possibly cake, and absolutely no stopwatch. This is a city that rewards an unhurried approach.

Heidelberg and Viking: make the most of your time

For Viking guests, Heidelberg may feature as an excursion from a Rhine itinerary rather than a river-ship stop in the city itself. The exact programme depends on the sailing and may involve a coach transfer, a guided walk and some independent time. Before you disappear into a shop on the Hauptstraße — easily done, I assure you — make sure you know where and when to meet your group. If you have the option of spending longer independently, Heidelberg is an excellent candidate for a return visit.

A few practical things worth knowing

The Hauptstraße and much of the Old Town are pleasant for walking, but cobblestones can be uneven. The castle and Philosopher’s Walk involve hills, steps or steep paths, so choose your route according to your comfort and mobility. Comfortable shoes are a better investment than heroic optimism. For current opening hours, funicular details and events, check Heidelberg’s official tourism website.

Questions guests often ask

How much time do I need? A few hours give you a taste of the Old Town and bridge; a full day lets you enjoy the castle and more leisurely wandering.

Is Hauptstraße really a mile long? It is approximately 1.6 kilometres long, running through the Old Town.

Did Mark Twain really live here? He stayed in Heidelberg for more than three months in 1878 and later wrote about it in A Tramp Abroad.

Is Heidelberg Germany’s warmest city? It is in a notably mild region, and the Philosopher’s Walk has an especially warm microclimate, but ‘the best climate’ is a matter of taste rather than an official title.

Is the Philosopher’s Walk easy? The classic approach from the Old Bridge is steep; allow time and wear good shoes.

Why Heidelberg stays with me

I have visited a great many cities, and some impress me more than they endear themselves to me. Heidelberg does both. Perhaps it’s the castle above the rooftops, perhaps the handsome villas across the Neckar, perhaps the lively students or that glorious mile of shops and cafés. Most likely it’s the combination. Whatever the reason, I never feel that Heidelberg is simply somewhere to tick off a list. It’s somewhere to enjoy being. And for me, that’s the best kind of travel.
