Will be on the bus out of Mals to Zernez and need to know if they are equipped with a WC. Thanks.
Hi timfogl, welcome to MySwissAlps!
I have never seen or heard about a regular bus service in Switzerland with an on board WC. There are toilets at the rail station of Zernez.
If one had an "emergency" I HOPE the driver would stop or otherwise the rest of the trip may smell pretty bad!!! Thanks Arno
