Narrow dark subglacial rather vertical canyon with southern orientation.
Accesso:
Flem-Express von Flims nach Segnes oder Fil da Cassons. Alternativ den Postbus von Laax-Bergbahn nach Alp-Nagens nehmen. October 2025 "the ideal canyoning season seems to fall in the off-season, when there are no cable cars or post buses running to Nagens/Segnes. The chairlift to Naraus don't exist anymore. I have checked with the relevant municipality to see whether driving permits for the road to Nagens can be issued/purchased. However, they have informed me that these are only issued for agricultural purposes. This means that from 19 October, Nagens can only be reached on foot or by mountain bike or maybe e-bike."

Giro (4 h):
Engagement Ausweichmöglichkeit am Ende des Plateaus vor der zweiten Abseilstelle mit Klettern rd; vor den großen Wasserfällen (Zugang über einen Pfad oberhalb der Klippe), wenn ein Seil installiert ist. Zeitraum/ Wassercharakter Subglazial, Gletscher mit südlicher Ausrichtung. Saison Oktober - November, vor dem Besuch muss es eine Woche lang trocken sein und die 0°C-Isotherme unter 2800m muss seit mehr als 24 Stunden bestehen. Geschichte Eröffnung 16.10.2010 Patrick Chollot, Evan Jenkins, Matthias Holzinger, Andreas Senn, Timo Stammwitz. Bemerkungen Ein zu breiter Kanister im Rucksack kann diesen blockieren. Stirnlampe nützlich, um zusätzlich zu sehen, aber nicht notwendig. Am C10 nach dem C25 im 2. Abschnitt (Swiss Alps Topo) kam es 2024 zu einem tödlichen Unfall aufgrund eines eingeklemmten Fußes. Ein vom Wasser verdeckter Schlitz kann hier zur tödlichen Falle werden. Am 19.10.2025 wurde die Stelle durch einen orografisch linksseitigen neuen Anker entschärft, der Anker Rechts ist aktuell noch vorhanden! Hier sollte bei Gelegenheit die Platte entfernt, aber der Bolzen mit Mutter erhalten bleiben. Siehe auch Bild in der Galerie.
Commitment Alternative route at the exit of the plateau in front of the second ropes course with climbing rd; in front of the large waterfalls (access via a path above the cliff) if a rope is installed. Period/ water character Subglacial, glacier with southern orientation. Season October - November, before the visit it must be dry for a week and the 0°C isotherm below 2800m must have existed for more than 24 hours. Opening history Opening 16.10.2010 Patrick Chollot, Evan Jenkins, Matthias Holzinger, Andreas Senn, Timo Stammwitz. Remarks A canister that is too wide in the rucksack can block it. Headlamp useful for additional visibility, but not necessary. On the C10 after the C25 in the 2nd part (Swiss Alps topographic view) there was a fatal accident in 2024 due to a trapped foot. A slot covered by water can become a deadly trap here. On 19.10.2025, the spot was defused by an orographic new anchor on the left side, the anchor on the right is currently still there! The plate should be removed here when the opportunity arises, but the bolt and nut should be retained. See also picture in the gallery.
