Ropewiki's Spanish language route notes call Zanaibach an impressive, very technical canyon in slate with no escape once inside; the walls run at least 50m for the whole descent.

No bail out point once committed: the walls stay at least 50m for the whole descent, so check the flow at the wooden footbridge before dropping in. Locals cap a safe descent around 150 liters per second. Bring 2x50m ropes, spare rigging hardware (maillons, cord), and a full wetsuit for cold water. Source note: the infobox lists Jul-Aug as the best season, but the route notes describe Zanaibach as a glacial canyon best run October through November, icing up by February. Worth confirming current conditions before relying on either.

Logistics

PermitRopewiki lists no red tape for this descent, but Swiss canyoning access is cantonal and this has not been confirmed with an official authority. Ropewiki also warns to evaluate flow carefully, with locals citing a maximum of about 150 liters per second before conditions turn.
