Here’s the bucket list for your day ashore: the most extraordinary thing to do at each stop, and the private, small-group, or expert-led way to make it yours — your own pace, real access, none of the crowd.
In port at Regensburg, the bucket-list move is Walhalla by Danube riverboat — the marble Hall of Fame above Donaustauf. Donauschifffahrt Wurm & Nö (Personenschifffahrt, official Regensburg operator) runs it — a private, expert-led experience at your own pace, not a 40-person coach. Below: all 6 bucket-list things to do on a Regensburg port day, each with the independent way to make it yours.
1landmark
Glide upriver from Regensburg's old town to Walhalla, King Ludwig I's blinding-white Doric temple modeled on the Parthenon, then climb the monumental staircase to a hall of marble busts honoring the great figures of German history. Arriving by water — the way it was meant to be seen — is the bucket-list version: the temple appears on the bluff exactly as Ludwig staged it, and the colonnade frames a sweeping bend of the Danube. It is one of the most theatrical neoclassical monuments in Europe and the single must-do beyond the old town itself.
Book it withDonauschifffahrt Wurm & Nö (Personenschifffahrt, official Regensburg operator)Boat round-trip EUR 21 adult (children 6-13 half price); Walhalla monument entry EUR 4.50 adult / EUR 3.50 reduced (under 18 free), paid at the door

Sail from Kelheim through the Donaudurchbruch, a narrow limestone gorge where 80-meter white cliffs close in over the green water, to Weltenburg — the oldest monastery in Bavaria (founded c. 620) and home to the world's oldest monastery brewery. The combination of the canyon passage, the baroque Asam abbey church, and a dark Weltenburger Kloster beer in the riverside courtyard is one of the Danube's genuine bucket-list half-days. The gorge stretch is protected and can only be seen by boat.
Book it withPersonenschifffahrt im Donaudurchbruch (Schifffahrt Kelheim, official gorge operator)Gorge boat Kelheim–Weltenburg round trip approx. EUR 17-19 adult (one-way approx. EUR 11); abbey courtyard and church free, beer/food extra

3history
Walk the most intact medieval city north of the Alps with an official guide — a thousand-year tangle of patrician tower-houses, Roman gates, and crooked lanes that survived WWII almost untouched, which is exactly why UNESCO listed the whole core. A licensed guide unlocks the layers an unguided stroll misses: the Roman Porta Praetoria, the merchant towers built to out-rank the neighbors, and the cathedral square. This is the foundation experience of any Regensburg call.
Book it withTourismus Regensburg (official city tourist office, Altes Rathaus)Public daily guided old-town walk EUR 8 per person / EUR 16 family (approx. 1.5 hrs); English walk typically 14:00 in season

4culture
Tour the private palace of the Princes of Thurn und Taxis, the dynasty that ran Europe's imperial postal monopoly for centuries and built a residence said to out-room Buckingham Palace. The guided route through the gilded state rooms, the throne room, and the Romanesque-Gothic cloister of the former St. Emmeram abbey is pure aristocratic Bavaria — a side of Regensburg most day-trippers never see. It is the city's most opulent interior and a standout for anyone drawn to living-dynasty grandeur.
Book it withFürst Thurn und Taxis (official palace, St. Emmeram)Combined palace ticket EUR 17 adult / EUR 14 reduced (children under 10 free); private small-group guide flat EUR 140 for under 10 people

Stand inside St. Peter's, Bavaria's purest Gothic cathedral, where original 13th–14th-century stained glass throws color across the nave and the Domspatzen — the world's oldest boys' choir, founded in 975 — still sing. Then walk the Steinerne Brücke, the 12th-century Stone Bridge that was an engineering marvel of its age and the model for medieval bridge-builders across Europe. Together they are the postcard of Regensburg and a free, unmissable pairing.
Book it withTourismus Regensburg (Cathedral & Stone Bridge, official info)Cathedral entry free (donation welcomed); official cathedral guided tour low single-digit EUR; Cathedral Treasury museum approx. EUR 3; Stone Bridge free

6history
Descend beneath the Neupfarrplatz square into an excavated cross-section of 2,000 years: the foundations of a Roman legionary fortress, the cellars of Germany's oldest documented Jewish quarter (recorded around 1000 AD, razed in 1519), and a Nazi-era ring bunker. A 14th-century hoard of 624 gold coins and the Jewish community's seal ring were found here. It is one of the most affecting and least-touristed experiences in the city — history you literally walk down into.
Book it withTourismus Regensburg (document Neupfarrplatz, official)Guided underground tour approx. EUR 8 per person (the only way to enter); approx. 1 hour
