Top sights near the Schwarzenberg Alluvial Canal

Lookout Tower Moldaublick

From the observation point atop the Sulzberg (1041 m), visitors can enjoy a stunning view of the Moldaustausee (Lipno Lake, Czech Republic) - one of the largest reservoirs in Europe - as well as Adalbert Stifter’s birthplace in Oberplan. The area of the Czech Republic visible from this vantage point was largely settled by the German-speaking population until the end of World War II, when Sudeten Germans were forced to evacuate. Today, the viewing tower erected by the municipality of Ulrichsberg offers a panoramic vista of the former homeland for those who were displaced and lost their homes.

The steep steps of the Schwarzenberg Alluvial Canal.

Here, the logs used to rush down the river during the snow melts with a thundering noise. This was the most dangerous point for the workers, because if a log got stuck, the ones that followed could be catapulted several feet into the air.

Start of alluvial canal

near Lichtwasser not far from the Bavarian border. In 1928, the Rosenauer Monument was unveiled at the home of the landowner Adolf Schwarzenberg. Not far from here you will find the Rosenauer-Klause.

Alluvial tunnel

Rosenauer's successor Ernst Mayer had the original 419 m long tunnel built. The tunnel runs through a mountain tongue at a depth of up to 15 metres. It is interesting to note that the upper portal was built in the neo-Gothic style and the lower portal in the neo-Renaissance style. The tunnel is a popular bat hibernation site, accessible at both ends but not walkable throughout.


Starting point for the Schwarzenberg alluvial canal and the Bärensteig nature trail. Canal Expo exhibition. The alluvial canal and folk dance meetings take place on fixed dates.

Rosenau Chapel 

and Seebach-Schleuse. In August, the Schemm pilgrimage fair takes place. Not far away is the Seebach-Riese, a fork of the Seebach.

Hefenkriegbach giant

A connection between the Schwarzenberg alluvial canal, the Vltava and the railway. Enabled the flooding of timber after the end of the Vienna Alluvial.


In 1835, at an altitude of 945 m above sea level, a Klause was built with a water supply of approx. 9000 m³ and connected to the alluvial channel and the 1.3 km long Hirschbach-Riese.

Rotbach sluice

on the state border between Sonnenwald and Zvonková (Glöckelberg). There are show floats on fixed dates.

Schrollenbach sluice

There are show floats on fixed dates.

Iglbach culvert and lock

on the state border. Show floats take place on fixed dates.

Rosenhügel sluice

On the main European watershed, the channel gradient changes from a few per mille of the slope channel to the natural gradient with up to more than 10 % in the escarpment. The flow velocity of water and wood is much higher in the natural gradient.

Main European watershed

in the former Rosenhügel. Here the construction of the Schwarzenberg alluvial valley was started in 1789.
