Mark Twain’s raft trip on the Neckar: truth or tall tale?
Germany’s lower Neckar Valley is Mark Twain country.
This stretch of river, the locals will fondly tell you, inspired Huckleberry Finn. The author came to Germany in 1878 with writer’s block and Huck Finn half finished. Twain’s raft trip down the Neckar River changed everything, at least according to the locals. Because afterward, Twain finished his novel.
But did that raft trip ever take place?
Historians come down on both sides of the question.
Twain’s raft trip in A Tramp Abroad
Twain’s travel memoir, A Tramp Abroad, covers his 1878 trip to Germany. With Heidelberg as a base, the author made side trips to Baden-Baden, the Black Forest, and several towns along the Neckar. From Heilbronn, a river port north of Stuttgart, he claims to have rafted back to Heidelberg. In fact, no less than six chapters are dedicated to Twain’s raft trip.
According to Twain in chapter 14, he’d intended to hide from Heilbronn back to the Heidelberg. But at Heilbronn’s bridge, he watched raft after raft float under the bridge:
The river was full of longs, — long, slender, barkless pine logs, — and we leaned on the rails of the bridge and watched the men put them together into rafts. These rafts were of a shape and construction to suit the crookedness and extreme narrowness of the Neckar. They were from 50 to 100 years long, and they gradually tapered from a 9-long breadth at their bow-ends.
On a sudden compulsion, Twain abandoned the idea of a pedestrian tour and chartered a raft himself. Twain’s two-day trip back to Heidelberg, writes Peter Messent, was a dress rehearsal for Huckleberry Finn.

The beautiful Neckar
The raft meandered along at about 2 miles an hour and Twain could enjoy being a tourist without doing the work of walking. His description in A Tramp Abroad sounds idyllic:
Germany, in the summer, is the perfection of the beautiful, but nobody has understood, and realized, and enjoyed the utmost possibilities of this soft and peaceful beauty unless he has voyaged down the Neckar on a raft. The motion of a raft is the needful motion; it is gentle and gliding, and smooth, and noiseless; it calms down all feverish activities, it soothes to sleep all nervous hurry and impatience; under its restful influence all the troubles and vexations and sorrows that harass the mind vanish away, and existence because a dream, a charm, a deep and tranquil ecstasy. How it contrasts with hot and perspiring pedestrianism, and dusty and deafening railroad rush, and tedious jolting behind tired horses over blinding white roads!
I’ve boated that stretch of the Neckar and can testify to his statement.

Could you even charter a raft in 19th-century Germany?
The 19th century saw plenty of rafts on the Neckar. The timber industry used rafts to transport logs from the Black Forest down steam all the way to the Netherlands. Although the railroad and chain tugs on the rivers reduced the number of rafts by 1878, they were still in use.
But could you charter one?
I asked two German museums dedicated to the regional rafting history and both indicated Twain’s raft trip was theoretically possible. Rafts were still running and they were known to taken on passengers. You can view a photo of a German raft with passengers here.
Could you pilot one?
Twain, however, went a step further in chapter 20. As the raft approached Heidelberg, Twain decided he could shoot the rapids under the bridge himself. “I went to the forward triplet of logs and relieved the pilot of his pole and his responsibility.” But that was the end of Twain’s raft trip. He stepped off the raft as it reached Heidelberg’s old bridge and the raft crashed and splintered against the pier. The passengers survived; Twain himself fished them out of the water.
That part of the story showcases the author’s humor, not his historical accuracy.
Piloting a raft required a great deal of strength. The untamed Neckar River sliced through the 19th century with rapids and difficult-to-navigate narrow passages. Only the strongest men were allowed to steer. Considering that his livelihood was at stake, it’s inconceivable the pilot would allow an inexperienced tourist to take over. His boss would have held him responsible for the lost logs.
So did Twain really travel the Neckar?
Definitely. In A Tramp Abroad, Twain’s descriptions of Neckar Valley towns like Heilbronn, Bad Wimpfen, and Hirschhorn are detailed and accurate enough he had to have been there. And in Dilsberg, he reported a story about a forgotten tunnel leading from the town well to a place in the woods outside the city walls. An American archaeologist investigating the story discovered the tunnel years later, and it’s now open to the public. How could Twain have known about the tunnel is he hadn’t visited the town?
But on a raft?
Maybe not. The river journey from Heilbronn to Heidelberg in A Tramp Abroad took place on a raft, but in Twain’s diary, Notes and Journals, Twain and his companion boarded a boat in Heilbronn on August 9, 1878. But the diary mentions the boat passing a raft about half a mile below the town of Eberbach. That leaves the truth about Twain’s raft trip a bit of a mystery. I like that. But both sources make it quite clear: The idea of river rafts floated on the surface of Twain’s consciousness during his trip on the Neckar.
Some say that the Neckar inspired one of America’s greatest novels; after he reached Heidelberg, Twain was able to finish chapter 16 of Huckleberry Finn. It’s the chapter in which Huck and Jim, on their raft in the Mississippi, realized they’d already passed Cairo, Illinois and Jim’s one shot for freedom.
But chapter 16 was already completed in 1876, according to Richard Bridgman (pp. 100-101). Twain picked up the manuscript again in 1880. He published Huckleberry Finn in 1885.
Regardless of the plausibility of Twain’s raft trip, it’s clear that river rafts played a prominent role in the author’s imagination. Peter Messent is right. Whether real or not, Twain’s raft trip on the Neckar was a dress rehearsal for Huckleberry Finn. And for that, we can be thankful.

Mark Twain: Why Germany is the Answer to Writer’s Block
It can happen to anybody. Mark Twain had started several new books when it struck in 1878. His solution to writer’s block might surprise you. And the results probably surprised him.
Mark Twain in Heidelberg
Twain decided a change of scenery would help and booked a 16-month trip to Europe with his family. He had already become famous for Innocents Abroad and his goal was to get away to a quiet place, where people didn’t know him. “I had a couple of light minor purposes, also: to acquire the German language, and to perfect myself in Art,” he wrote.
Heidelberg offered the perfect refuge. On the Königstuhl Mountain, perched high over the city, Twain found an inn where he rented a room as an office. Further downhill, he booked a $250 per month suite for his family in the Schloss Hotel. He lived there for several months. The view from his hotel distracted him from his writing, but later inspired him. In a May 26, 1878 letter to his friends, he wrote:
… divinely located. From this airy porch among the shining groves we look down upon Heidelberg Castle, and upon the swift Neckar, and the town, and out over the wide green level of the Rhine valley—a marvelous prospect. We are in a Cul-de-sac formed of hill-ranges and river; we are on the side of a steep mountain; the river at our feet is walled, on its other side, (yes, on both sides,) by a steep and wooded mountain-range which rises abruptly aloft from the water’s edge; portions of these mountains are densely wooded; the plain of the Rhine, seen through the mouth of this pocket, has many and peculiar charms for the eye.
Neckar River as Distraction and Inspiration
Our bedroom has two great glass bird-cages (enclosed balconies) one looking toward the Rhine valley and sunset, the other looking up the Neckar cul-de-sac, and naturally we spend nearly all our time in these—when one is sunny the other is shady. We have tables and chairs in them; we do our reading, writing, studying, smoking and suppering in them.
The view from these bird-cages is my despair. The pictures change from one enchanting aspect to another in ceaseless procession, never keeping one form half an hour, and never taking on an unlovely one.
At some point Twain looked beyond the beauty of the Neckar River to its commercial activity. Log rafts floated down regularly from the Black Forest. Twain sketched them and described them in A Tramp Abroad. In August, 1978, he took a trip upstream to Heilbronn and returned, in part, by boat, but his fantasy was working the entire trip. Twain concocted a story about a return trip in a raft.
Raft Trip on the Neckar River
While I was looking down upon the rafts that morning in Heilbronn, the dare-devil spirit of adventure came suddenly upon me, and I said to my comrades:
“I am going to Heidelberg on a raft. Will you venture with me?”
Twain claims to have chartered a raft for his return trip and describes a myriad of adventures on the return trip: boys swimming out to them, a naked beauty bathing under a willow tree, a storm, and a shipwreck.
Germany, in the summer, is the perfection of the beautiful, but nobody has understood, and realized, and enjoyed the utmost possibilities of this soft and peaceful beauty unless he has voyaged down the Neckar on a raft.
Inspiration for Huckleberry Finn
Back in Heidelberg, Twain got fresh inspiration for Huckleberry Finn. He had already been toying with the raft trip idea, but now his ideas crystallized. He wrote chapter 16, in which Jim and Huck take off on the raft but missed Cairo in the fog, in Heidelberg.
Twain’s biographer Justin Kaplan views the fictional raft trip on the Neckar as a crucial remedy to the writer’s block that stalled Huckleberry Finn. A German river might have inspired one of the greatest works of American fiction. It would be no surprise to the Germans, who consider the Neckar the most “literary” of all its rivers. Friedrich Schiller, author of the Ode to Joy and William Tell, was born on its banks. Goetz of Berlichingen, who inspired Goethe, had a castle on the Neckar.
Can’t write? Then come to Germany!
