    Slovenia, the EU and Schengen: what it means for British visitors

    Facts checked on

    Quick answer

    Yes, Slovenia has been in the European Union since 1 May 2004, in the euro since 1 January 2007 and in the Schengen area since 21 December 2007. For British travellers that means the 90-in-180-day rule, passport registration under the EU's Entry/Exit System at the external crossings and the occasional temporary check at internal borders.

    Slovenia in the EU, in short

    Full read: 2 min

    • Slovenia joined the EU and NATO in 2004.
    • It adopted the euro on 1 January 2007 and joined Schengen on 21 December 2007.
    • UK travellers follow the 90-in-180-day rule and go through the EES at airports.
    • Temporary checks are possible at some internal borders.
    What I would do

    Schengen doesn't mean you'll never be asked for your passport. I'd always carry it, even for a half-hour hop to Gorizia or into Croatian Istria, which is exactly when people leave it at the hotel.

    Before you go

    Before you go to Slovenia, this

    1. 01 My tip

      Open borders, with occasional checks

      The Tourist Board mentions temporary checks on the borders with Croatia and Hungary, and the FCDO refers to Italy and Austria. Which crossing is checked depends on government decisions at the time.

      A square shared with Italy

      Europe Square (Trg Evrope), in front of Nova Gorica station, is shared by Slovenia and Italian Gorizia, according to the Tourist Board. To me it's the most photogenic internal border in the country.

      The GHIC works here

      As an EU country, Slovenia accepts the UK GHIC or EHIC for medically necessary treatment in the public system, according to the FCDO. It doesn't replace travel insurance.

    What I would check before going

    UK passports in Slovenia

    Since Brexit, British visitors are third-country nationals in Schengen. The FCDO’s rules are the familiar ones, a passport that’s less than a decade old and still valid three months after you leave, and no visa for up to 90 days out of every 180, counted across the whole area, so days in Italy or Croatia on the same trip count too. For health, the GHIC or EHIC covers medically necessary treatment in the public system, but the FCDO is clear that it isn’t a substitute for insurance.

    Are there border checks?

    Schengen doesn’t mean borders with no checks ever. According to the Tourist Board, Slovenia has brought back temporary controls at its Croatian and Hungarian borders and that Austria checks its own side, while the FCDO mentions checks with Italy and Austria and asks people coming from Croatia or Hungary to use crossings open to all travellers. Which frontier is checked at any moment is a government decision, so I’d never leave my passport in the hotel. The full rules are in Slovenia entry requirements.

    The Entry/Exit System

    The Tourist Board says the EU’s Entry/Exit System has been in force since 10 April 2026 at the country’s five external border points, of which three are airports and two are ports. It records non-EU visitors biometrically, and the FCDO warns of longer waits and says the registration remains valid for three years. If you’re flying into Ljubljana, build some extra time into your first evening.

    The euro and Schengen, in 2007

    On 1 January 2007 the euro replaced the national currency, and on 21 December of the same year Slovenia joined the Schengen area, according to the EU’s country page. It now has nine MEPs and has chaired the Council of the EU twice, in the first half of 2008 and the second half of 2021. The Slovenian government sums up Schengen’s effect as borders losing much of their importance and cross-border cooperation becoming part of daily life. Paying in euros is covered in Slovenia currency.

    From independence to the EU

    It happened fast. After independence in 1991, Slovenia joined the Council of Europe on 14 May 1993 and opened EU accession talks on 31 March 1998, wrapping them up in December 2002. A referendum on 23 March 2003 backed joining both the EU and NATO, and both came in 2004, NATO on 29 March and the Union on 1 May. The longer story, from Roman Emona to independence, is in the history of Slovenia.

    If you are short on time, see the best tours in Nova Gorica and pick one that fits your day.

    A border you can walk across

    There’s one place where all this becomes very tangible. Right outside Nova Gorica station is Trg Evrope, Europe Square, split between Slovenia and Italian Gorizia, as the Tourist Board explains. I can’t think of a clearer demonstration of what Schengen means in practice, and you’ll find it in Nova Gorica.
