Opening dates of Switzerland’s pass roads

Closures in winter and in bad weather

In winter, many passes are closed. Driving conditions can be difficult on passes that remain open, like the Simplon, Brünig and Julier Pass. There may be snow on the road. I advise traveling by train instead. In some cases, you can avoid pass roads by using tunnels or car trains.

Passes may temporarily close in case of bad weather. This can occur at any time and any place, also for passes that are normally open year-round.

What if driving is not safe or not possible?

Switzerland has an excellent network of trains and other public transport. It’s a safe, scenic, and eco-friendly alternative to traveling by car. Please find all details here.

Note that there are many places that can not be reached by car, either because cars aren’t allowed there, or because there’s no road. A Swiss Half Fare Card helps you save money on tickets for trains and cable cars to such places. You will also save on boat tickets for the Swiss lakes.
