In the Guaraqueçaba Portal, you will find some of the best-preserved areas of the Atlantic Forest in the entire Great Reserve. The jaguar inhabits its dense forests, alongside other large mammal species such as the tapir, the white-lipped peccary, and the puma. Guaraqueçaba was one of the first points reached by the Portuguese during colonization; it was here that the history of Paraná began.

Time may have passed, but the town still retains much of its original character, including old colonial houses, the central square facing the bay, and the caiçara culture, which can be witnessed in traditional boats or Fandango circles. Access to the Portal can be made by boat from Paranaguá or, for the more adventurous, via the PR-405—a 78 km unpaved road. Along the way, several communities can be visited, such as Tagaçaba, Potinga, Serra Negra, Rio Verde, Batuva, and Morato, among others.
