The Portal Nascentes do Iguaçu is located in the municipalities of Campina Grande do Sul, Colombo, Pinhais, Piraquara, Quatro Barras, and São José dos Pinhais — where the Afonso Pena International Airport is situated. The territory partially covers the Iguaçu, Ribeira, and Coastal hydrographic basins, where the Iraí, Piraquara, Capivari, and Miringuava dams are located, which are responsible for supplying more than 3 million people.

Essa rede hídrica é formada por rios e afluentes de extrema importância — como o Iguaçu, o Piraquara, o Iraí, o Pequeno e o Miringuava — que, além de garantir segurança hídrica, criam uma paisagem natural de rara beleza. As Cataratas do Iguaçu tem origem nesta região. Esses ambientes sustentam uma rica diversidade de fauna e flora, inclusive trechos de Floresta com Araucária, ecossistema ameaçado e símbolo do sul do Brasil.

The Portal stands out as a destination for nature tourism, with various routes for cycle tourism, mountaineering, birdwatching, waterfalls, water sports, and hiking trails. The strong presence of rural colonies, local producers, and traditional communities makes the region a fertile territory for rural and community-based tourism.
