The San Rafael Hills (Serranía de San Rafael) are located in southeastern Paraguay, spanning the departments of Itapúa and Caazapá, and represent one of the country's most vital ecological refuges. This hilly range is part of the Paraná Plateau and is characterized by gentle slopes covered by the original Atlantic Forest (Bosque Atlántico del Alto Paraná). Covering over 70,000 hectares, the region hosts exceptional biodiversity, including more than 400 bird species, many of which are endemic or endangered. Geologically, the area is predominantly composed of basalt shaped by millennia of erosion. San Rafael National Park was established in 1992 to protect this critical habitat from advancing deforestation driven by agriculture. Beyond its ecological role, the area serves as an important water catchment and reservoir for the surrounding rural communities.

📋 Practical info
Getting there
This gently rolling hill country located in southern Paraguay is generally highly accessible via rural dirt roads that conveniently connect various distinct parts of this key ecological corridor.
Best season
The historically lower-rainfall months between May and September are practically well-suited for pleasant walks and nature observation, allowing visitors to avoid muddy paths and see rich flora.
Terrain & paths
The terrain predominantly consists of deeply undulating, grassy hills and patches of woods, which typically permit unchallenging, low-gradient hikes along frequently completely unmarked paths.
What to bring
Sturdy, completely closed footwear is highly advisable due to potential insects and very tall grass; additionally, always carry binoculars for birdwatching and sufficient mosquito repellent.
Parking
Parking spaces are most commonly and reliably found near small peripheral communities or close to local ranger stations, which act as primary contact points within this sprawling large area.
Safety
Since it is a deeply crucial ecological corridor, disturbing the local wildlife must be strictly avoided; tick protection and fully closed clothing are heavily recommended due to tall grass.
Time needed
Visitors frequently utilize the area for highly relaxing half-day excursions or peaceful picnics, though enthusiastic naturalists and avid birdwatchers certainly spend completely full days here.
