Teyú Cuaré is a small nature park on the bank of the Paraná river near San Ignacio in Misiones; its Guaraní name means «lizard cave». Created in 1991, it protects rock cliffs and dense forest overlooking the wide river and the Paraguayan shore opposite. Its best-known feature is the tall Peñón rock above the river, reached by a forest trail to viewpoints, including the Reina Victoria lookout, with the whole sweep of the river below. Scientists say the park holds Argentina's only pocket of Cerrado, the tropical savanna of central Brazil. These landscapes inspired the Uruguayan writer Horacio Quiroga, who lived nearby; his house is now a museum close by. Entry is free with an optional donation, 09:00-18:00, with a visitor centre and campground. Combine it with Quiroga's house and the San Ignacio ruins in a day.
