Heidelberg

Serendipity brought us to Heidelberg. Friends we met through the HomeExchange program casually suggested we consider an exchange there, and we eagerly accepted despite knowing almost nothing about the city. In retrospect, that lack of expectations may have made the experience all the sweeter. Heidelberg turned out to be one of those rare places that quietly captures your heart — romantic without trying too hard, youthful yet historic, cultured but entirely approachable.

Germans themselves often describe Heidelberg as one of the country’s most romantic cities, and after a few days wandering its cobblestone lanes beneath the castle ruins, it is easy to understand why. The city escaped much of the destruction that befell Germany during World War II, leaving behind an unusually intact old town of Baroque buildings, church spires, riverside promenades, and red-roofed vistas climbing the hillsides above the Neckar River. Writers, poets, philosophers, and painters have been drawn here for centuries. Even Mark Twain fell under its spell.

Another surprise was Heidelberg’s distinctly international feel. The city has long had a large American presence because the U.S. Army established its European headquarters here after the war. While much of the military infrastructure has since closed or been repurposed, the legacy remains. English is widely spoken, menus are often bilingual, and the city feels unusually comfortable for English-speaking visitors. Combined with the university population and international researchers, Heidelberg has a cosmopolitan ease that makes settling in remarkably simple.

As always, our introduction to the city came through a walking tour booked on GetYourGuide. Our guide, Jessica — a former German history professor at Heidelberg University who left academia to raise her children — was superb. She possessed that rare ability to combine scholarship with humor and anecdote, making centuries of history feel alive rather than academic. For those less inclined to walk, another delightful option in this highly pedestrian city is the open-air Cabrio sightseeing bus, which winds through the old town and hillsides with wonderful views.

During our walks we learned of Heidelberg’s long history of invasions and wars. The city was repeatedly overrun during conflicts involving the French, the Holy Roman Empire, Protestants, and Catholics. One of the more striking stories involves the Church of the Holy Spirit in the center of town, which for a time literally had a wall erected down the middle so Catholics and Protestants could worship separately under the same roof. Germany does not shy away from difficult history, and Heidelberg’s layered past is everywhere if you pay attention.

Dominating much of city life is Heidelberg University, Germany’s oldest university, founded in 1386 and consistently ranked among the country’s finest research institutions. Today roughly 24 percent of Heidelberg’s 150,000 residents are students, and the university profoundly shapes the city’s atmosphere. There is an unmistakable youthful energy here — casual cafés filled with students, vegan restaurants beside centuries-old taverns, posters plastered across walls advertising lectures, concerts, theater, and political debates. It gives Heidelberg a liveliness many historic cities lose over time.

One of the city’s great pleasures is ascending above it. The funicular railway climbs from the old town up to the famous castle ruins, itself one of the great Renaissance ruins in Europe. From there, a second and far steeper historic tram continues higher into the forested hills. The views become progressively more spectacular as the city and river spread below you.

Even Heidelberg’s hillsides contain reminders of darker chapters. Above the city sit the remains of a large Nazi-era amphitheater built for propaganda gatherings during the Third Reich. Further uphill lie the evocative ruins of St. Michael’s Monastery, hidden in the forest and well worth the extra climb. The contrast between peaceful woodland paths and the weight of history below is deeply moving.

Of course, the city’s most famous walk is the Philosopher’s Path, or Philosophenweg, a roughly two-hour hillside route overlooking the old town and castle across the river. Scholars and philosophers from the university supposedly walked here seeking inspiration, and one quickly understands why. The views are postcard-perfect nearly the entire way, especially in the late afternoon light.

One of Heidelberg’s true hidden gems is the remarkable Sammlung Prinzhorn, housed within the university psychiatric clinic. The museum’s outsider art collection consists largely of works created by psychiatric patients in the early 20th century and became enormously influential on Surrealist and Expressionist artists. The collection is haunting, intimate, and unlike any museum experience we have had elsewhere in Europe.

For a more traditional museum experience, the Kurpfälzisches Museum on the main pedestrian street offers an excellent overview of regional history, decorative arts, archaeology, and fine art.

One particularly touching moment captured the spirit of the city for us. During our walking tour we stumbled across University Square filled with small medical tents occupied not by patients, but by children carrying stuffed animals — mostly teddy bears. Medical students were gently “treating” the toys to help children learn not to fear doctors or hospitals. It was thoughtful, charming, and somehow deeply German in the best possible sense.

For dining, Heidelberg exceeded expectations. One especially atmospheric traditional German restaurant near the Old Bridge was Wirtshaus zum Nepomuk, full of dark wood, candlelight, and exactly the sort of romantic charm one hopes to find in Heidelberg. Equally memorable, though entirely different in tone, was Red – Die Grüne Küche, an elevated vegetarian restaurant that rivaled excellent modern restaurants in London or San Francisco.

For breakfast, pastries, or an afternoon coffee break, we especially loved Café Schafheutle along the main walking street, with its beautiful outdoor courtyard shaded by trees and flowers. Also worth a stop is Café Knösel, the city’s oldest café.

One of Heidelberg’s stranger attractions is the famous Student Prison, or Studentenkarzer, where university students were once jailed for offenses ranging from dueling to public drunkenness. Because students retained considerable social status, many treated imprisonment almost as a badge of honor, covering the walls with elaborate drawings and graffiti that still remain today.

We also took several day trips from Heidelberg that were highlights in themselves.

Most essential is Schwetzingen Palace, often overshadowed by larger German palaces but absolutely enchanting. The palace gardens are spectacular, blending French formality with English landscape traditions, and include one of Europe’s most beautiful “mosque follies,” built purely for romantic and aesthetic purposes during the Enlightenment. One important tip: check carefully which days English-language tours of the palace interiors are offered. During our visit they were only available on weekends. We joined a German-language tour and still loved seeing the rooms, though we admittedly missed much of the historical explanation.

Another wonderful excursion was a three-hour round-trip cruise on the Neckar River aboard the White Fleet boats. The ticket included unlimited coffee, soft drinks, and wine — an offering many passengers enthusiastically embraced as we drifted past castle ruins, vineyards, and tiny riverside villages. We chose to disembark at Neckarsteinach for a couple of hours before catching the return boat. After a lovely riverside lunch at Jaber’s Restaurant, we hiked uphill to visit two of the four castles that make this tiny town famous. Insider tip: pack snacks, as during our sailing only drinks were served onboard.

Another gem is the Mark Twain Center, which explores both Twain’s affection for Heidelberg and the broader German-American relationship. Twain spent significant time here and wrote lovingly — and humorously — about the city and German culture.

One afternoon we drove to the small riverside town of Neckargemünd, which sits quietly along the Neckar and feels far less touristy than Heidelberg. Half-timbered houses, riverside walks, and a slower pace make it an easy and relaxing escape. From there we continued uphill to Dilsberg, a tiny former walled village perched dramatically above the valley with sweeping views in every direction. It feels almost impossibly picturesque, as though someone constructed a miniature storybook town on the mountaintop. Lunch at Hotel Restaurant Sonne was especially memorable, featuring the season’s first white asparagus.

Sadly, we ran out of time before exploring Mannheim and its enormous palace, as well as the towns of Weinheim and Erbach, both highly recommended to us by locals.

For a uniquely Heidelberg souvenir, seek out the famous “Student Kiss” chocolates, beautifully boxed sweets that supposedly originated when male students slipped romantic notes inside before presenting them to young women. Essentially the 18th-century equivalent of texting.

One final observation. Visitors may initially notice what appears to be a surprising lack of upkeep in some parks, gardens, and green spaces. Lawns are often left partially wild, flowers intermingle naturally, and areas can seem intentionally overgrown by American or British standards. But this is increasingly deliberate throughout Germany. Many municipalities now embrace more naturalistic landscaping to encourage biodiversity, pollinators, and healthier urban ecosystems. What at first glance can appear untidy soon begins to feel thoughtful, ecological, and quietly beautiful — much like Heidelberg itself.
