DESCENT AT YOUR OWN RISK! The best way to get into the ravine is from the south or from the bridge up the stream. There you will find a collapsed cave and a second one, which is still accessible for a good 15m until the groundwater makes it difficult to go any further. Brown coal was mined here from 1842 until the end of the First World War, in a good 336m tunnel.

Standing on the viewing platform at the Seerenbach Falls, you are almost awed by the thundering waterfalls. From here you can see the vertical rock face and the waterfalls cascading down into the valley. They are only topped by the white, foaming Rin spring right next to it.

A short hiking trail from Betlis leads to the gigantic Seerenbach Falls, which at a height of 600 meters are among the largest waterfalls in Europe. The Seerenbach Falls can be seen from afar, thundering down the vertical rock face in three stages. Gigantic spectacle of nature The best view of all three levels of the waterfall is from the chapel in Betlis. The middle of the three cascades is one of the highest free-falling waterfalls in the world with a height of 305 meters. Refreshing destination Coming from Weesen or Quinten, the Seerenbach Falls with the source of the Rin are a special highlight of every hike. It is a short hike from the picturesque village of Betlis to stand on the viewing platform at the foot of the third cascade and watch the roaring waterfalls up close. In warm weather, they provide cool refreshment. In spring after the snow has melted or after heavy rainfall, the Seerenbach Falls are particularly impressive due to the large amounts of water. Mystery source of Rin Where the Seerenbach falls imposingly fall into the valley, they unite with the Rinquelle, one of the largest karst springs in Europe. At the beginning of the 20th century, researchers began to study the source of the Rin and the cave system that branched out for kilometers. There is a turnoff about three kilometers from the cave entrance. From here the water disappears inside the mountain. Where? That will probably remain a secret.

Very nice place, nice furnishings and the cave can be discovered on your knees after the entrance, then immediately while crouching! Definitely epic for a swim there, but was a little too frosty for me with the snow and ice.
