FCO Argentina travel advice: what Brits should check

If you search for ‘FCO Argentina’ before a trip, the Argentina travel advice you need is now published by the Foreign, Commonwealth & Development Office (FCDO) on GOV.UK. The FCO changed its name in 2020. Even if Buenos Aires is home, the live warning and the separate safety, entry requirements and health sections are useful before a long weekend away or a border crossing.

The warning may change quickly, and the distinction between ‘against all travel’ and ‘against all but essential travel’ can affect insurance cover. Read the current wording for your destination against your policy's exclusions rather than an old search snippet or saved screenshot. The FCDO provides travel and consular advice; Argentine immigration decisions belong to Migraciones.

Start with the journey you are taking

For a domestic trip, the safety and security section gives the broader picture on protests, strikes and crime, while the health section covers regional risks and vaccination guidance. GOV.UK offers email updates from the country page. A local forecast and transport operator then supply the detail a country warning cannot give you about a particular road, flight or departure.

For an international crossing, read the Argentina entry requirements as well as the FCDO advice and government entry rules for the other country. The ferry from Buenos Aires to Colonia enters Uruguay; visiting the Brazilian side of the falls from Puerto Iguazú enters Brazil. A weekend abroad does not automatically start a fresh 90-day tourist allowance in Argentina: an immigration officer decides re-entry. The Colonia day-trip guide deals with the practical ferry crossing.

British passport holders ordinarily enter Argentina visa-free as tourists for up to 90 days (September 2026). Migraciones offers one paid extension of up to 90 days, while tourist entry does not permit local employment. Residents returning with an Argentine residence card or pending-residence document have a different document question from visitors arriving on a tourist stay. For a domestic flight, the carrier's accepted photo-ID rules and the name on the booking matter too. The first-week Buenos Aires checklist covers the paperwork that follows arrival.

Cover and care away from home

The FCDO health advice describes travel risks, but the insurer's policy determines the cover. Hiking, skiing, car hire and evacuation can each have conditions of their own; it helps to have the assistance number, policy number, passport details and prescription names available offline. A prepaga (private healthcare plan, closer to Bupa than the NHS) does not automatically provide overseas travel insurance.

Under DNU 366/2025, Argentine public hospitals can charge non-residents for non-emergency care. Emergency care remains free, and residents with a DNI (national identity document) retain free public care, subject to provincial rules. In illness abroad or far from home, the insurer's assistance line can arrange a referral and explain payment; the British Embassy is a source of consular help rather than medical cover.

What changes beyond Buenos Aires

In the capital, bags on the Subte (metro), phones near the kerb and demonstrations around Plaza de Mayo or Congreso deserve attention. Marches can disrupt roads and public transport; a confrontation or police line is a place to leave alone. For everyday neighbourhood habits, the Buenos Aires safety guide for families has more local detail.

Outside the city, the journey itself shapes the risks. Patagonia can mean wind, remote roads and long distances without fuel or signal. Altitude, cold and changing weather matter on hikes around Mendoza, while heat, mosquitoes and wet walkways matter at Iguazú. The FCDO health section carries current regional disease notices; Argentina's national meteorological service, SMN, publishes forecasts and alerts. A bus company or driver can tell you about the road conditions on the day.

For a flight, check whether the ticket says Aeroparque Jorge Newbery on the Buenos Aires waterfront or Ministro Pistarini at Ezeiza outside the city. On a road trip, a hire company can tell you which licence and supporting document it accepts, whether the policy covers the intended route and what happens on unpaved roads. Passports and luggage are safer out of sight in a parked car; on a coach, documents and medicine belong in the bag you keep with you rather than the hold. An offline map and accommodation address help where signal is patchy.

A weekend at Iguazú, on paper

For two adults living in Palermo and planning three nights in Puerto Iguazú, a September 2026 planning allowance might be US$600 for two return flights, US$300 for accommodation and US$180 for food and transfers. That totals US$1,080, or about ARS 1,668,600 at ARS 1,545 per US$. These are allowances, not advertised fares; dates and booking lead time affect the actual price. A quote of ARS 1,800,000 would exceed that allowance by ARS 131,400.

The choice to cross to the Brazilian side adds another country's entry rules to their plans. The departure airport, FCDO safety and health advice, SMN forecast and the passport matching each ticket all have a bearing on this particular journey. Keeping the return itinerary, accommodation address and insurance assistance number offline means the details are to hand if one of them needs a doctor.

When a trip goes wrong

In the City of Buenos Aires (CABA), 911 reaches police, 107 reaches SAME ambulance services and 100 reaches the fire service. Give a street number, nearest cross streets, floor and flat; Necesito una ambulancia en... means ‘I need an ambulance at...’. Emergency arrangements can differ outside CABA, so local numbers matter when travelling. In immediate danger, local emergency services are the first contact.

After a theft, getting somewhere safe and blocking cards and the SIM comes before a police denuncia (formal report); the report number can help with insurance. For a lost UK passport, GOV.UK has an Emergency Travel Document application for urgent travel, and the British Embassy in Buenos Aires handles consular enquiries. Airlines and transit countries set their own requirements for a replacement document. The Embassy can help you understand the next consular step, while Migraciones decides Argentine border and residence questions.
