At the Marco das Três Fronteiras, the Iguaçu River flows into the Paraná, and Brazil, Argentina and Paraguay meet within sight of each other. On the Brazilian bank, a landmark obelisk painted in the national colours marks the spot, and a riverside park with lookouts, fountains and information panels explains the history of the region and the Jesuit missions. Argentina's Hito sits across the water to the south, and Paraguay's marker is visible on the opposite bank. In the evening, dancers and musicians perform a cultural show, and there are food stalls, a restaurant and a children's play area. The setting is at its best around sunset, when the rivers glow and the three countries are lit. It is not a place for a full day, but an hour or two is pleasant, especially if you are staying in Foz and want an easy outing after the falls.
The viewpoint costs a modest entry fee, which a Viator listing gave as fifty-five reais for adults in 2024, with lower prices for children and seniors and free entry for small children and Foz residents. Prices change, so confirm before you go. The Viator ticket linked here is the landmark admission, with decent review numbers, and several other listings add sunset transport and dinner, which suits travelers without a car.
The experience is gentle rather than spectacular. The big draw is symbolic: standing where three countries meet, with a view of two rivers and the obelisks on the other banks. Photographs are most satisfying in the golden hour, and an evening visit often includes the cultural show. Take a light layer for the breeze off the river, insect repellent for the dusk, and cash for small purchases.
If you are crossing the border during your trip, you can also visit the Argentine Hito Tres Fronteras in Puerto Iguazú, which has a similar view from the other side, a craft fair and a light show. Doing both in one trip lets you compare and costs less than a Paraguayan excursion. Do not confuse either with the commercial centre of Ciudad del Este; the landmarks are about the geography and history, not shopping, and they pair well with an easy sunset dinner.
