Interrail Passes can only be used by European citizens and permanent residents of Europe. You'll find the full list of participating countries below, plus loads of other useful information. If you're a UK resident, Brexit doesn't affect the Interrail Pass. You can still purchase and use one as normal.

Yes, British citizens and residents can absolutely still use Interrail in 2026. There is a common misconception that Interrail is tied to European Union membership, but it is actually managed by the Eurail Group, which is owned by over 35 European railway companies. The UK's exit from the EU (Brexit) did not change its status within the Interrail network. British travelers can purchase an Interrail Global Pass to travel across 33 different countries, or a One Country Pass for specific nations. One unique rule for UK residents is the "Inbound/Outbound" rule: you can only use your Interrail pass for two journeys in your home country (Great Britain)—one to leave at the start of your trip and one to return at the end. This usually covers the Eurostar from London St. Pancras to Paris or Brussels, though keep in mind that the Eurostar requires a mandatory seat reservation fee which is not included in the price of the Interrail pass itself.
