Can I travel to Switzerland without ETIAS or a visa after 2026?

Yes, for now, UK citizens can travel to Switzerland without ETIAS because ETIAS is not yet active. But starting from late 2026, UK citizens will need an ETIAS for short stays of up to three months. You will be denied entry without an approved ETIAS once the system is enforced.

As this is a regulated system to track travel visits, those who do not need a visa for short stays in any Schengen country. However, for longer stays or work purposes, you will still need to apply for the appropriate Schengen visa from UK.
