The Pau Oco State Park has an area of 905.58 hectares (2,237.7 acres) in the municipality of Morretes, Paraná.

[2] The park contains the Salto da Fortuna, a waterfall that may be reached by a trail taking about four hours round trip.

The trail is of medium difficulty, crosses rivers, and includes sections and ruins of the old Arraial Colonial Route, now replaced by BR-277.

The land was owned by the Environmental Institute of Paraná (IAP), who was responsible for promoting preservation of the water, flora and fauna.

Two years were allowed for preparation of the management plan, which was to be integrated with the Marumbi Special Area of Tourist Interest.
