Teyú Cuaré Provincial Park

This place stands out for its huge stone walls over 200 metres high on the Paraná River, which make up one of the most noteworthy landscapes amidst the rainforest.
Several medium difficulty trails offer magnificent views of the river and the neighbouring lands of Paraguay. The hike to the top is through a staircase made of rock blocks, which may be quite demanding and require stops for you to catch your breath. The panoramic views you will get are well worth the effort.
The place has toilet facilities, but no shops where you can buy food.
