Tres Fronteras Landmark: Argentina's Triple Border Marker

Direct answer: The Tres Fronteras Landmark is Argentina's triple‑border marker in Puerto Iguazú, on the confluence of the Iguaçu and Paraná rivers, from where Brazil and Paraguay can be seen. Access is free and it is a few blocks from downtown — you can walk there. It features an obelisk, viewpoints, and a craft market, and just below the landmark operates El Hito Restaurant, offering food and a sunset view. Do not confuse it with the Brazilian landmark (in Foz) nor the Paraguayan one.

What it is

It is the Argentine vertex of the three‑country border — an obelisk painted in Argentina's colors, aligned with the twin landmarks of Brazil (the Three Borders Landmark in Foz) and Paraguay. From the viewpoints you see the meeting of the Iguaçu and Paraná rivers and, across the water, the Brazilian and Paraguayan territories. In addition to the monument, there is a craft market, regional products, and cafés.

Hours and admission

Access to the Hito area on the Argentine side is free — agencies sell paid tours, but entry costs nothing. The site is open throughout the day; the viewpoint and market have no fixed hours. The highlight is the view of the three countries from the lookouts.

El Hito Restaurant — dining with a view

Just below the landmark operates El Hito Restaurant, a gourmet overlook with a terrace and panoramic windows facing the confluence of the Iguaçu and Paraná rivers, with Brazil and Paraguay ahead. It serves regional cuisine, wines and drinks, and is one of the best spots to watch the sunset over the three countries with a drink in hand. Open Wednesday to Monday; reservations via WhatsApp +54 9 3757 46-5136.

How to get there

It is located in the center of Puerto Iguazú, a few blocks away — you can walk along the waterfront, take a taxi or local bus. No tour is required.

What this means for you: go in the late afternoon to catch the sunset over the three countries, the most beautiful moment; if you want to linger, El Hito Restaurant right below offers the same view with food and drinks.
