At the foothills of the imposing Pico Paraná, the highest peak in southern Brazil, lies the Vale do Gigante Portal. The region takes its name from the mountain range visible across the entire plain, whose silhouette resembles that of a giant resting figure. The municipality of Antonina has been encouraging the region to expand the range of attractions available to visitors. Today there are many options, including accommodations, restaurants, local guides, adventure sports (such as rafting and canoeing), hiking, wildlife and plant observation, handicrafts, organic and agroecological products, honey from native bees, and cultural activities.

Several communities are working together in this effort, including Bairro Alto, Cachoeira de Cima, Cacatu (the cradle of Japanese colonization in Paraná), Rio do Nunes, and Faisqueirinha. Visitors can reach the region via PR-340, a paved road that also leads to the historic Governor Pedro Viriato Parigot de Souza Hydroelectric Plant.

The area also includes two large privately owned protected areas.
