Day trips from Frankfurt
5 stopsBest: May to October for the Rhine. The rest works all yearUpdated July 2026
No other German city is so well placed for leaving. The main station has nearly thirty platforms and from here ICEs run to Cologne in an hour, regional trains to Heidelberg in fifty minutes and trains to the Rhine in thirty. If you came for work and have a spare day, there’s no excuse.
And there’s a move worth knowing before you book the hotel: the airport has a high-speed station of its own, so you can spend a whole day away and come straight back to check in without entering the city. Few people use it and it changes what fits into a short trip.
The route, stop by stop
5 STOPS- 01
The Rhine valley
The stretch between Bingen and Koblenz runs sixty-five kilometres and holds some forty castles, which works out at one every kilometre and a half, and they aren’t there out of romanticism: every lord with a crag charged a toll on the boats passing underneath. The Rhine was a motorway with booths, and the booths were fortresses.
The way to see it is from the water: train to Rüdesheim or Bingen, get on a scheduled boat, get off wherever you fancy. In the middle is the Loreley, the hundred-and-thirty-metre rock where the river narrows and turns dangerous, and hence the legend of the woman who sang and sank ships.
The legend is nineteenth-century. The wrecks were real.

Heidelberg
Heidelberg delivers what people picture when they think of Germany and almost never find: a river, a hill, a half-ruined red castle and a university from 1386, the country’s oldest. It escaped the bombing, which is why the old town is genuine: the exception rather than the rule in this country.
The castle is a ruin because the French blew it up twice in the seventeenth century and because afterwards it was decided not to rebuild: the nineteenth-century romantics worked out that a ruin moved people more than a whole palace, and the town took their advice. Inside there’s a wine barrel holding two hundred and twenty thousand litres that got used three times.
At fifty minutes by train, it’s Frankfurt’s best-value day out.
- 03
Mainz and the printing press
Half an hour away sits the town where Johannes Gutenberg set up, in the 1440s, the workshop that changed how everything works: movable metal type. The museum that carries his name holds two complete Gutenberg Bibles out of the forty-nine left in the world, and runs a replica press several times a day.
The other thing here is a thousand-year-old red sandstone Romanesque cathedral, and the windows of St Stephen’s church, made by Marc Chagall at the end of his life: solid blue, and he accepted the commission as a Jew in postwar Germany, which is half the reason they matter.
Mainz takes half a day and pairs well with the Rhine, which starts directly opposite.
- 04
Cologne
An hour by ICE puts you at the largest Gothic cathedral in northern Europe, which greets you off the platform: the station is literally at its feet. It was begun in 1248 to hold relics of the Magi, stopped in 1560 with the crane still on top, and stayed like that for three hundred years, crane and all, until the nineteenth century decided to finish it from the original plans. It was completed in 1880.
It survived the war because it was a navigation landmark for the bombers, while the city around it ceased to exist: there are photographs of the cathedral standing in a field of rubble that explain the whole of Cologne.
It’s the long trip on this list and it fills the day, with the advantage that the ICE also stops at Frankfurt airport on the way back.
- 05
Wiesbaden and Darmstadt
Wiesbaden sits half an hour away and offers everything Frankfurt lacks: a nineteenth-century spa town that wasn’t bombed, with a casino, a theatre and thermal water the Romans already used.
You go in the afternoon, you walk, you come back. It’s the short lazy escape and it works on a Sunday.
Darmstadt is odder and more interesting: in 1899 the grand duke invited a group of artists to set up a colony on a hill, the Mathildenhöhe, to make new architecture. What came out is one of the most complete Art Nouveau ensembles in Europe and it’s a world heritage site. Half an hour by train, and almost nobody knows about it.
Frequently asked
What day trip can you do from Frankfurt?
Heidelberg in about fifty minutes by train, Mainz in thirty, the Rhine valley a little more and Cologne an hour by ICE. It’s the best-connected German city for leaving: the main station has nearly thirty platforms.
How do you visit the Rhine valley from Frankfurt?
By train to Rüdesheim or Bingen and from there on a scheduled boat, getting off where you like. The stretch between Bingen and Koblenz has some forty castles in sixty-five kilometres: they were toll booths over the river, not romantic whimsy.
Can you do Cologne in a day from Frankfurt?
Yes, it’s an hour by ICE and fills a day. The ICE also stops at the airport’s long-distance station, so if you fly in the evening you can come straight back to check in without going through central Frankfurt.
