Sierre-Zinal route detour
A detour has been implemented to ensure your safety while allowing you to continue your preparations.
(see the map below).
You can check open routes on SuisseMobile.ch.
The trail is open up to Hôtel Weisshorn from Sierre via Chapelle St-Antoine only (closed between Sierre and Niouc).
Due to several potential hazards, such as rockfalls, partially blocked paths, and damage caused by the Navizence flood, the Sierre-Zinal race course will be closed from April 28 to June 30, 2025.
