This article is an itinerary.

The Main Donau Kanal (Main-Danube Canal) also known as the Europakanal ("Europe-canal") or the Rhein-Main Donau Kanal (abbreviated RMD) is mostly in Franconia (Upper and Middle Franconia and partly in Bavaria (Lower Bavaria and two short stretches in Upper Palatinate). It links the Danube with the Main, a tributary of the Rhine. Its official end to end length is 170.71 km (106.07 mi).

This canal started construction in the 1960s and was finally opened along its full length in 1992. It was originally intended as a freight link, linking - as was said at the time, grandiosely but not inaccurately - North Sea and Black Sea via the river system of Main, Rhine and Danube. The Canal reaches the highest point directly reachable via oceangoing vessel in the world. Even still, the railroad and trucking play a vastly larger role in the freight business along its entire stretch and the canal never earned in usage fees what its upkeep and maintenance costs. An unintended consequence of its construction is converting inland cities like Nuremberg into cruise ports and river cruises have become an important business factor even though the freight business is largely an afterthought. The canal is also a frequently used hiking and biking route with decent trails along its (relatively flat) banks and several bridges and underpasses from one side to the other. It is also open to and used by various sports clubs who use rowboats and other human powered watercraft on the canal. There are also some Yachting clubs along the canal.

Attempts to link Main and Danube. Except the "Mindorfer Linie" built during the Nazi era, they all were open to ships of some kind from end to end at some point in time. Naturally, the RMD allows the biggest ships of all extant and former canals.

Interestingly, the canal represents the third completed attempt to link Danube and Main (or their tributaries) for shipping of some kind. The first, Fossa Carolina was built under Charlemagne in the 8th century CE and was long thought to have been abandoned before completion until archeological findings proved otherwise. The second one Ludwig Donau Main Kanal was built under the rule of Bavarian King Ludwig I who was skeptical of the newfangled railway and instead preferred to have a canal built. While it did carry a few goods all the way to its end in the 1950s, it soon proved too small and too outdated to compete with the railways. While parts of that canal still hold water and the former towpaths where burlaks or horses would tow the ships towards their destinations still exist along much of the way and are today popular hiking and bike paths, the canal is not passable for boats along its entirely length and indeed part of it has been filled in to build the new A73 motorway, including ironically the site of a monument celebrating the completion of the canal.

A secondary purpose of the current canal is to enable the transport of water from the usually rather wet Old Bavaria into Franconia. The Franconian Lake District is a set of largely artificial lakes that also serve this purpose.


The easiest ways to experience the whole length of the canal is booking a cruise that goes through its entire length or taking a bike trip along the path of the canal. The paths next to the canal mostly serve maintenance needs but have since become a popular bike and hiking path and are even part of the daily commute of some people in "bike-crazy" towns like Erlangen

Get inEdit

This image, taken near Nuremberg illustrates the touristic value the canal has gained. However, scarcely a cargo ship is to be seen.

The Canal links the Main river near Bamberg in Upper Franconia with the Danube near Kelheim in Lower Bavaria. The former is served by numerous regional trains and even the occasional ICE. Nuremberg Airport (NUE IATA) is the closest international airport to the canal and Nuremberg has a harbor for both cargo and cruises, but it sits more or less in the middle of the canal so starting any trip there only enables you to take half of the itinerary. Kelheim has lost all passenger train service in 1988, but if you head a bit further down the Danube, there are plenty of places that are more accessible.


Map of Main Donau Kanal

This itinerary starts in the North at Bamberg even though it can naturally be done in both directions. As mentioned above, Bamberg is far easier to get to than Kelheim. In general, major ports are called Hafen whereas more moderate installations are called Lände.

  • 1 Hafen Bamberg. Giving access to both Main river and Canal.  
  • 1 Lände Erlangen.  
  • 2 Lände Fürth.  
  • 2 Hafen Nürnberg.  
  • 3 Lände Roth.  
  • 4 Lände Mühlhausen.  
  • 5 Lände Dietfurt.  
  • 3 Hafen Kelheim. The southern endpoint of the Canal

Given that the canal crosses the European main watershed and passes through comparatively mountainous terrain, there are quite a few locks. The German term "Schleuse" is used here for them. Watching a boat getting lowered or raised can be interesting to observe whether you are on the boat or not.

  • 1 Schleuse Bamberg. Counting from the North, this is the first Schleuse and it lifts or lowers the watercraft by 10.94 m (35.9 ft). The height towards the Main river is 230.9 m (758 ft).  
  • 2 Schleuse Strullendorf. Lifting and lowering boats by 7.41 m (24.3 ft)  
  • 3 Schleuse Forchheim.  
  • 4 Schleuse Hausen.  
  • 5 Schleuse Erlangen. As the original 1960s structure is now at the end of its design life, there has been an effort since 2014 to rebuild it while keeping ships running.  
  • 6 Schleuse Kriegenbrunn. From here it is the longest distance to the next Schleuse on a southward journey - 20.43 km (12.69 mi)  
  • 7 Schleuse Nürnberg.  
  • 8 Schleuse Eibach.  
  • 9 Schleuse Leerstetten. Lifting boats by 24.67 m (80.9 ft) this is the first of three (counting from north to south) to reach this, the maximum height difference ever reached on locks in Germany.  
  • 10 Schleuse Eckersmühlen. Passing a rather major height difference in a short distance, this Schleuse together with the next one Southward has a height difference of 24.67 m (80.9 ft) each, combining for almost fifty meters.  
  • 11 Schleuse Hilpoltstein. Once you pass this point on your southward journey, you have reached the highest point of the Canal. The surface of the water between this and the next Schleuse reaches a height of 406 m (1,332 ft), the highest point directly reachable from the ocean on a seagoing vessel in the world. Lifting and lowering watercraft by 24.67 m (80.9 ft), it is one of three along this canal that reaches such a height difference - the largest ever built in Germany.  
  • 12 Schleuse Bachhausen. When traveling from North to South, you are here lowered some 17 m (56 ft) towards the lower height of the Danube, having passed the highest stretch of the canal.  
  • 13 Schleuse Berching. Built in 1991, this is the youngest one along the canal.  
  • 14 Schleuse Dietfurt.  
  • 15 Schleuse Riedenburg.  
  • 16 Schleuse Kelheim. Coming from the north, this is the last Schleuse along the canal, lowering you a final 8.4 m (28 ft) towards the final height of 338.2 m (1,110 ft)  

Stay safeEdit

There are signs on the paths next to the canal that "entering them is on your own risk" and you should rather not fall into the water, as it may be difficult to get out, but other than that you should be safe.

Go nextEdit

Obviously as this canal links Main and Danube, you can head on along those rivers if you have a watercraft or explore Upper Franconia or Lower Bavaria respectively.
