The San Rafael Reserve represents the largest remaining fragment of the Interior Atlantic Forest in Paraguay, spanning the departments of Itapúa and Caazapá. Covering approximately 73,000 hectares, it hosts an extraordinary biological diversity, including over 400 documented bird species. The area was officially designated as a protected reserve in 1992 to safeguard its primary forests and natural grasslands from agricultural expansion. Geographically, the reserve serves as a critical watershed for the Tebicuary River and plays a significant role in regulating the local microclimate. Beyond its ecological importance, San Rafael is home to indigenous Mbya Guaraní communities who maintain an ancestral connection with the forest. Despite international conservation efforts, the area faces constant threats from illegal logging and man-made forest fires. For researchers, San Rafael is considered one of the most vital ecological laboratories in the Southern Cone.

📋 Practical info
Getting there
Approach is typically via rugged agricultural tracks from Karonay or Yoseb; the frequently harsh dirt roads generally necessitate a tough four-wheel-drive vehicle to navigate successfully.
Best season
A visit is highly recommended between May and October, as temperatures are noticeably milder and the likelihood of heavy rainfall is significantly lower compared to the sweltering summer.
Terrain & paths
The landscape features dense, hilly Atlantic forest with thick, impenetrable undergrowth; the unmarked natural trails are highly rustic, frequently overgrown, and quite demanding to traverse.
What to bring
Indispensable gear includes high bite-resistant hiking boots, durable long pants, heavy-duty insect repellent, and plenty of drinking water, as local visitor infrastructure is extremely limited.
Parking
Formal parking lots are largely absent; vehicles can usually be safely parked near ranger stations or at neighboring private eco-lodges after prior consultation with the friendly local staff.
Safety
Leaving the established trails must be strictly avoided due to the dense vegetation and high risk of getting hopelessly lost; additionally, remain alert for wild animals and illegal logging activities.
Time needed
For a profound nature experience, visitors typically plan a one- to three-day excursion, most often combined with stays at rustic accommodations situated around the edges of the vast reserve.
