The UK Foreign, Commonwealth & Development Office (FCDO) refreshed its Switzerland travel advice on 21 July 2026, adding detailed guidance on disruption expected around the G7 leaders’ summit, which will be held just across the border in Évian-les-Bains, France, from 15–17 June 2026. Although the summit itself is a month away, the update reflects the Swiss authorities’ advanced security preparations, which include the temporary closure of several secondary border crossings with France and reinforced checks at the main crossings in the Geneva region. According to the notice, travellers driving or commuting between France and Switzerland can expect “severe delays” on the days immediately before, during and after the summit. The Republic and Canton of Geneva has confirmed that closures could apply from 12–19 June, and that diversions and rolling roadblocks may affect both freight routes and local public-transport lines. Previous G7 events have generated queues of up to three hours on the A40/A1 motorway corridors, and hoteliers in the Geneva area are already reporting near-full occupancy for the summit week. The FCDO specifically flags risks for business travellers with tight schedules, advising companies to avoid routing staff through minor crossings such as Sézegnin, Certoux and Monniaz, which are likely to be sealed entirely. Logistics providers have been encouraged to shift time-sensitive consignments to rail freight or to larger customs posts such as Bardonnex that will remain open 24/7 under enhanced staffing. Airlines operating at Geneva Airport have been told to expect VIP movements that could lead to air-traffic-control flow restrictions of up to 30 minutes during peak arrival slots. Beyond physical border measures, Swiss police have granted permits for authorised demonstrations in central Geneva on Sunday 14 June, but the FCDO notes that “unauthorised protest activity” may flare up at short notice. Employers should brief mobile staff on situational awareness and maintain WhatsApp or SMS check-in protocols, particularly for employees unfamiliar with the city’s multilingual emergency-services system. For mobility managers, the advisory is a reminder that Switzerland, although part of the Schengen zone, retains the right to re-introduce internal border controls temporarily for security reasons. Multinational firms scheduling leadership off-sites, investor roadshows or trade-fair visits in the French-Swiss border region during the second half of June should revisit their travel risk assessments. Contingency plans might include flexible rail tickets on the TGV Lyria network, reserving parking at larger crossings, and building additional buffer time into meeting agendas. The updated guidance can be viewed on the FCDO website, and the Canton of Geneva has launched a bilingual micro-site with live maps of closures and alternative routes.
