Hito Tres Fronteras: Argentina's triple border marker

Direct answer: The Hito Tres Fronteras is Argentina's triple border marker, in Puerto Iguazú, above the confluence of the Iguaçu and Paraná rivers, looking out over Brazil and Paraguay. Entry is free and it sits a few blocks from the centre, within walking distance. There is an obelisk, viewpoints and a crafts market, with El Hito Restaurante just below. Do not confuse it with the Brazilian marker in Foz, which charges admission and only opens at 2pm, nor with the Paraguayan marker in Presidente Franco.

What it is

It is Argentina's corner of the three-country border: an obelisk painted in the national colours, aligned with its twins in Brazil and Paraguay. From the viewpoints you see the Iguaçu and Paraná rivers meeting and, across the water, Brazilian and Paraguayan territory. Beyond the monument there is a crafts market, regional products and cafés.

Access to the Hito area is free. Agencies sell paid tours there, but entry itself costs nothing.

The three markers, side by side

Each country has its own obelisk, and this is where itineraries usually break. They do not keep the same hours, and one closes before another opens.

Note the clash: the Paraguayan one closes at 6pm and the Brazilian one only opens at 2pm. Anyone wanting all three in a day has a narrow afternoon window, plus two border crossings in between. Arrive in the morning and only the Paraguayan and Argentine markers are open.

They also differ in concept: the Brazilian site is a paid complex built around sunset, with performances; the Argentine and Paraguayan ones are straightforward viewpoints.

The Paraguayan marker, which almost nobody covers

It sits in Presidente Franco, about 3 km from the centre on Avenida Bernardino Caballero, on the way to Puerto Tres Fronteras. The municipality has run it since 2013 and charges G$5,000, a symbolic amount that funds upkeep.

There are steps down to the viewpoint and also a ramp for disabled visitors or anyone who would rather avoid stairs, plus parking, toilets and a playground. For the guaraní rate, see the live exchange rates.

El Hito Restaurante: the view with a meal

Directly below the Argentine marker is El Hito Restaurante, a gourmet lookout with a terrace and panoramic windows facing the river confluence, Brazil and Paraguay ahead. It serves regional cooking, wines and cocktails, and is one of the best sunset spots on the Argentine side.

Getting there

From central Puerto Iguazú you can walk: it is only a few blocks. Coming from Foz means crossing the Tancredo Neves Bridge with identification: check the live bridge queue and what documents you need.
