Overview
Mbaracayú Forest Nature Reserve (Reserva Natural del Bosque Mbaracayú) sits in the department of Canindeyú in eastern Paraguay, near the Aguaray Guazú River. Covering roughly 64,000 hectares, it protects one of the most significant surviving patches of the Upper Paraná Atlantic Forest, an ecosystem that has been reduced to a small fraction of its original extent across Brazil, Argentina, and Paraguay.
The reserve was established with support from The Nature Conservancy and is now managed by the Paraguayan non-profit Fundación Moisés Bertoni. It was recognized as a UNESCO Biosphere Reserve in 2000, underscoring its importance not only for biodiversity conservation but also for the traditional communities, including Aché and Ava Guaraní peoples, who live within and around its boundaries.
For travelers willing to venture off the standard tourism circuit, Mbaracayú offers a genuinely remote encounter with subtropical forest. Expect dense canopy, rivers, wetlands, and grassland-forest mosaics rather than polished infrastructure. This is a working conservation area first, a tourist destination second — and that is precisely its appeal.
Before You Go
Permits and Access
Mbaracayú is a protected reserve with restricted public access. Visits are generally coordinated through Fundación Moisés Bertoni, which manages the reserve. Contact the foundation in advance to arrange any visit — independent drop-in access is not standard practice here. Verify current entry requirements and any permit fees directly with the foundation before travel, as these details change and published figures quickly become outdated.
Visas
Paraguay's entry requirements vary by nationality. For current, accurate visa information, check TravelerPulse's Visas section and the official website of Paraguay's Dirección General de Migraciones.
Health and Vaccinations
Yellow fever vaccination is widely recommended for travel to forested areas of Paraguay; verify requirements with a travel health clinic well before departure. Carry mosquito repellent with DEET, long-sleeved clothing, and any personal medications. The nearest hospitals are in cities such as Curuguaty or Salto del Guairá — medical facilities in the immediate area are very limited.
What to Pack
- Lightweight, long-sleeved shirts and trousers (sun and insect protection)
- Sturdy waterproof boots suitable for muddy trails
- Rain gear regardless of season
- High-SPF sunscreen and quality insect repellent
- Sufficient cash — ATMs are scarce in surrounding towns; verify locally
Getting There
From Asunción
Mbaracayú is located approximately 300–350 km northeast of Asunción. The most practical route involves traveling by road toward Curuguaty (department of Canindeyú), using Highway 3 (Ruta 3) and then connecting roads. The drive can take five to seven hours depending on road conditions and the specific entry point to the reserve.
Public Transport
Bus services operate between Asunción and towns in Canindeyú such as Curuguaty. From those towns, onward transport to the reserve's access points is limited and largely informal. Verify current schedules and routes at bus terminals before travel, as services and operators change. Hiring a vehicle or joining an organized excursion from Asunción or Ciudad del Este is often the more reliable option.
From Ciudad del Este
Ciudad del Este, Paraguay's second-largest city, lies roughly 100–150 km south of the reserve area and may serve as a practical staging point for travelers arriving via the Friendship Bridge from Foz do Iguaçu, Brazil. Road connections exist but verify routing locally, as conditions on secondary roads can deteriorate significantly in the wet season.
Getting Around
Within the reserve, movement is on foot along trails or by vehicle on unpaved internal tracks. A guide is strongly recommended — both for safety and because navigating dense subtropical forest without local knowledge is genuinely difficult. Fundación Moisés Bertoni can advise on guided options when you arrange your visit.
Road conditions throughout Canindeyú vary considerably with rainfall. A high-clearance vehicle, ideally four-wheel drive, is advisable for reaching and moving around the reserve, particularly between November and March.
Where to Stay
Accommodation options at or immediately adjacent to the reserve are very limited. Fundación Moisés Bertoni operates a field station within the reserve that has hosted researchers and some organized visitor groups; contact the foundation directly to determine whether overnight accommodation can be arranged for your visit and under what conditions.
The nearest towns with more conventional lodging options include Curuguaty and, further south, Salto del Guairá. Facilities in these towns are modest. Travelers seeking greater comfort may prefer to base themselves in Ciudad del Este and make the reserve a long day trip or multi-day excursion. Verify current availability and pricing locally or through tour operators, as this area lacks established online booking infrastructure.
Things to See & Do
Wildlife and Birdwatching
Mbaracayú supports an exceptional diversity of species. Mammals recorded in the reserve include tapirs (Tapirus terrestris), giant anteaters, giant armadillos, pumas, and several species of peccary and deer. The birdlife is equally remarkable, with hundreds of species documented, making it a serious destination for ornithologists and committed birdwatchers. Early morning walks along forest edges and riverbanks yield the best sightings.
Hiking and Trail Walks
The reserve contains marked trails of varying lengths passing through different habitat types — dense interior forest, gallery forest along waterways, and cerrado-adjacent grasslands. Trail conditions and availability should be confirmed with Fundación Moisés Bertoni before arrival.
River and Wetland Exploration
The Aguaray Guazú and other watercourses within the reserve support wetland habitats that add to the overall biodiversity. Depending on the season and arrangements made with reserve management, short boat or canoe excursions may be possible — verify this locally.
Cultural Engagement
The reserve area is home to Aché and Ava Guaraní communities. Any interaction with these communities should be respectful, consensual, and ideally facilitated through the foundation rather than independently arranged. Responsible tourism here means following the lead of local and foundation contacts.
Practical Information
Money
Paraguay uses the Paraguayan Guaraní. Carry sufficient cash before leaving Asunción or Ciudad del Este — ATM availability in Canindeyú towns is limited and reliability is not guaranteed.
Connectivity
Mobile coverage within the reserve itself should not be assumed. Signal may exist in surrounding towns but can be patchy. Download offline maps (such as Maps.me or Google Maps offline) before departure.
Emergency Services
Emergency infrastructure in this remote area is minimal. In Paraguay, the general emergency number is 911, though response times in remote rural areas will be significantly longer than in cities. The nearest hospital-level care is in larger towns; confirm the nearest medical facility with your local contacts before entering the reserve.
Best Contacts
- Fundación Moisés Bertoni: the primary point of contact for all reserve visits (verify current contact details on their official website before travel)
- Paraguay's national environmental authority (MADES) oversees protected areas nationally
Safety
Mbaracayú is a remote area and standard wilderness precautions apply. Inform someone of your itinerary and expected return before entering the forest. Do not hike alone, and always travel with a knowledgeable guide.
The primary risks are environmental rather than security-related: difficult terrain, river crossings that can become dangerous in high water, insects (including vectors of diseases such as dengue and leishmaniasis), and the heat and humidity of the subtropical climate. Treat all water before drinking, use insect protection consistently, and be conservative about your physical limits on trails.
The reserve and surrounding region are generally considered safe from a crime perspective, though as with any rural area visitors should take sensible precautions with valuables and remain aware of their surroundings.
Local Culture & Etiquette
The reserve sits within a landscape shaped by both Guaraní traditions and more recent agricultural frontier history. The Aché people, historically hunter-gatherers of the Atlantic Forest interior, have an especially direct relationship with this landscape. Their presence and land rights are integral to the reserve's legal and social framework — not a backdrop to the visitor experience.
When visiting, respect signage and restrictions without question. Do not photograph individuals without clear, explicit permission. Purchasing handicrafts or produce from local communities, when offered through appropriate channels, can provide direct economic benefit. Spanish is the working language in towns; Guaraní is widely spoken and a few basic phrases of greeting are genuinely appreciated.
