Here is the old Schwarzwasser bridge, which leads over the river Schwarzwasser. The stone bridge offers some sights worth seeing. On one side of the bridge, the water has formed impressive channels and crevices in the sandstone slabs. On the other side, a small island offers a pleasant opportunity to use the river as a bathing spot in the summer. Further ahead, the newer Schwarzwasser bridge can be seen.

The Buvette offers a nice terrace with a good view over the hills. It is the right place for the biker break.

Finally – the ramp for slow-moving traffic is currently under construction. From the end of 2026, the steep ramp next to the stairs and the artwork by Richard Serra will finally be accessible.

There is a great, bilingual book about the creation of the Schiffenen reservoir, over which the viaduct runs, with many pictures of the time before the Saane was dammed. It also has portraits of contemporary witnesses who had roots in the Saane valley. The book was published in 2012 by the O.S.K.A.R. association. Orders can be placed on the website: www.verein-oskar.ch

Gäggersteg, simply brilliant. Very well done, with safe paths through the area and forests. The climb is relatively steep. Good footwear recommended. A must if you are in the region. For young and old.

The Grandfey Viaduct on the railway line from Bern to Freiburg is one of the largest bridges in Switzerland. It was built between 1858 and 1862 and is 334 m long and 82 m high. With the electrification of the Swiss Federal Railways' rail network, the bridge had to be reinforced in order to be able to carry the heavier and faster locomotives and train compositions. Based on a concept by Robert Maillart, the pioneer of large concrete structures in Switzerland, the Grandfey Viaduct was given its new design between 1925 and 1927.
