Explore Paraguay’s rugged Serranía San Luis National Park—clear streams, rare species sightings, and rugged Cerrado landscapes in the Concepción region.
Why Visit Serranía San Luis?
Far from the beaten path lies Parque Nacional Serranía San Luis, a wild and underexposed gem in northern Paraguay. Nestled between the Apa and Aquidabán rivers in Concepción Department, this 10,237-hectare protected area offers solitude, biodiversity, and an unfiltered connection with nature. It’s where rugged rocky hills meet cerrado savanna, clear streams, and rare wildlife, adventure begins before you even step foot inside.
Location
- Where: San Carlos del Apa district, Concepción ≈ 540 km north of Asunción (about an 8-hour drive via Ruta 5)
Dramatic scenery & waters
Serranía San Luis is defined by granite ridges: Serranía San Luís, Siete Puntas, Paiva, Guaicurú, interwoven with cerrado vegetation and seasonal watercourses. The terrain, with its rocky base, isn’t suitable for agriculture, but supports unique forest species like the endangered trébol tree, which thrives in rocky outcrops.
One of its most scenic features is the Tagatiyá stream, celebrated for its crystal-clear waters, perfect for snorkel-style surface diving and adventure tourism. Trails near the stream reveal vibrant wildlife and refreshing views along the way
Biodiversity & rare wildlife
The park is increasingly vital for biodiversity conservation:
- Home to rheas (ñandú), ynambú guazú (tinamous), macaws, and Pristine Cerrado fauna.
- In May 2025, researchers confirmed the first-ever documented sighting of the jagua yvyguy (Speothos venaticus)—a rare, endangered “vinegar dog”—in the park after more than four decades.
- Other notable species include jaguar, puma, maned wolf, giant anteater, tapir, Chacoan peccary, and many reptiles and rodents adapted to dry forests.
Importantly, over 219 bird species have been recorded in these Cerrado lands, three threatened and four near-threatened species are present.
Park facilities & conservation efforts
Today, the park includes:
- Ranger stations, visitor centres, and labs for environmental education and biodiversity monitoring.
- A national management plan published in July 2023, aligned with Paraguay’s Vision 2030 development strategy.
- Declared of national environmental interest due to threats from illegal logging, deforestation, and land conversion.
Tips for travellers
- Language: Spanish and Guaraní are the only widely spoken languages. English guides can be arranged.
- Timing: Best wildlife visibility is in the dry months (May–October). Budget extra time for dusty roads.

Why this park matters
Serranía San Luis protects a fragile Cerrado ecosystem, a transitional zone between dry Chaco and humid eastern landscapes. Its combination of biodiversity, geological complexity, and pristine waterways offers a rare chance to connect with Paraguay’s wild side.
