At the foot of the imposing Pico Paraná, the highest point in Southern Brazil, lies the Vale do Gigante Portal (Giant’s Valley Portal). The region is named this way because the mountain range, seen from across the plains, resembles the silhouette of an enormous sleeping being. The municipality of Antonina has encouraged the region to offer an ever-increasing range of attractions to visitors. There are already many, including accommodations, restaurants, local guides, adventure sports (such as rafting and canoeing), hiking, flora and fauna watching, handicrafts, organic and agroecological products, native bee honey, and cultural activities.

Several communities have been working together: Bairro Alto, Cachoeira de Cima, Cacatu (the cradle of Japanese colonization in Paraná), Rio do Nunes, and Faisqueirinha. Visitors can reach the area via the PR-340, a paved road that also leads to the old Governor Pedro Viriato Parigot de Souza Hydroelectric Power Plant.

There are also two large protected areas under private ownership.
