Bietschtal Bridge

Highlight • Bridge

The Bietschtalbrücke is a railway bridge of the Lötschbergbahn (BLS) on the so-called southern ramp. It spans the Bietschbach gorge at a height of 78 meters and is 136 meters long. The steel bridge was built between 1910 and 1913, the steel parts were only connected with rivets, not welded. Technically, mastering the forces in the curved track layout (radius 300 meters) with simultaneous incline was particularly demanding.

On the Südrampenweg, the bridge can be crossed on a side footbridge, a shorter route variant. The circumnavigation on the slightly longer path that leads further into the gorge (Via Alpina route) is particularly impressive, but requires a minimum of surefootedness and a head for heights.

Bietschtal Bridge on the Lötschberg Southern Ramp

Highlight • Bridge

The hiking trail along the southern ramp of the Lötschbergbahn (BLS) is walked in the classic way from Hohtenn to Brig, in two to three days. A particularly beautiful section is the path from the Bietschbachtal with the Bietschtalbrücke to Ausserberg. Wide views over the Rhone Valley, famous for the rich flora and fauna with its sub-Mediterranean character. In addition, the bisses, water intakes and the railway with its bridges, tunnels and auxiliary structures. You can spend a lot of time there.

The path is well marked and cannot be missed. Again and again information boards on the building history and landscape as well as rest areas (e.g. Riedgarten), flyers with maps at the train stations. Difficulty level T2.

Suonen Water Channel

Highlight • Structure

The historic irrigation canals of Valais are called bisses. They consist of open ditches or canals made of wood, which bring the water from the mountain streams to the pastures and fields, to the vineyards or to the orchards. Many of the bisses are still in use today.
