Is travel insurance required to visit Puerto Iguazú?

Direct answer: For a day trip from Foz do Iguaçu to Puerto Iguazú, sightseeing, eating or shopping and returning the same day, you do not need to show insurance. Argentina's entry requirement targets those who will stay. But there is a second rule, more recent and more concrete: since 12 August 2026, Argentine public hospitals charge non-resident foreigners for care that is not an emergency. Life-threatening emergencies are still treated immediately, with no payment up front.

Two rules that are not the same thing

Almost everything written about this mixes up two different things. Separating them:

1. The entry rule (Decree 366/2025). Published in the Official Gazette on 29 May 2025, the decree amended article 20 of Migration Law No. 25,871. It provides that a foreigner seeking admission presents a sworn declaration stating the purpose of the trip and that they hold health insurance.

2. The hospital rule (Resolution 1066/2026). This is the implementing regulation, from Argentina's Ministry of Health, in force since 12 August 2026. It establishes that, in facilities run by the National State, a foreigner without permanent residency receives ordinary care only on presentation of health insurance or prior payment of the fee.

The first is border paperwork, with an exception. The second is the one that touches your wallet.

Day trips are exempt

Short temporary visits, the classic crossing from Foz to see the falls on the Argentine side, have dinner or shop at the duty free, do not need to present insurance on entry. The requirement was designed for those staying in the country.

Even so, bring identification and check what is required in do you need a passport for Puerto Iguazú.

What changes if you fall ill over there

Here is the part that "it is not required" hides.

If you need a consultation, a scan or any care that is not an emergency, the Argentine public hospital may require insurance or payment before treating you. With neither, you pay out of pocket.

Emergencies are an explicit exception, and it is written down. The resolution expressly excludes from charging any service intended to assess, diagnose, stabilise and immediately treat a clinical condition involving certain and imminent risk to life. The text lists situations such as cardiac arrest, severe trauma, acute stroke and obstetric emergencies.

In other words: nobody will be left untreated in an emergency for lack of insurance. What changes is everything that is not an emergency.

So is it worth having?

It depends how long you stay:

The maths is simple: one consultation or imaging scan paid out of pocket in another country costs more than insurance for the whole trip.

Before you cross

Border rules change, and this one changed twice in little over a year. Always confirm on the official Dirección Nacional de Migraciones website before travelling.
