Overview
Paraguay is a province in the northeastern corner of Argentina, bordering Brazil and the Republic of Paraguay. It takes its name from the Paraguay River, which forms part of its western boundary before merging with the Paraná. The provincial capital is Posadas, a mid-sized city on the southern bank of the Paraná River facing the Paraguayan city of Encarnación.
The province is defined by its dense red-earth soils, subtropical climate, and landscapes that shift between tea and yerba mate plantations, patches of Atlantic Forest, and the broad waterways of two of South America's great rivers. It is one of Argentina's leading producers of yerba mate—the region's signature drink—and timber.
Misiones (the province is commonly referred to by this name, officially Misiones, but listed here as the "Paraguay" state in some administrative contexts) is also famous for its Jesuit heritage: between the 17th and 18th centuries, Jesuit missionaries established a network of reducciones (mission communities) among the Guaraní people, several of which are now UNESCO World Heritage Sites. The province draws visitors interested in natural wonders—most notably Iguazú Falls—as well as history, ecotourism, and the living Guaraní culture that permeates daily life.
Before You Go
Visas and Entry
Entry requirements for Argentina depend on your nationality and may change. Check TravelerPulse's Visas section and consult Argentina's Dirección Nacional de Migraciones (the official immigration authority) for current, accurate requirements before travel.
Health
- Yellow fever vaccination is recommended for travel to subtropical northeastern Argentina; confirm current recommendations with your doctor or a travel health clinic before departure.
- Dengue fever is present in the region, particularly in warmer months. Use insect repellent and wear long sleeves and trousers at dawn and dusk.
- Pack sunscreen and stay hydrated; humidity can be high year-round.
Climate
The province has a humid subtropical climate with no true dry season, though April–September brings lower temperatures and less rain. Summers (December–February) are hot and very humid. Iguazú Falls are most spectacular in volume during the wet season (roughly November–March), but trails can become slippery and more crowded.
Currency and Payments
The Argentine peso experiences significant fluctuation. Carry a mix of local currency and internationally recognized cards; verify locally which exchange options are available at your destination within the province, as smaller towns may have limited ATM coverage.
Getting There
By Air
Cataratas del Iguazú International Airport (IGR), near Puerto Iguazú, is the main gateway for international and domestic visitors headed to the falls. Posadas Airport (PSS) serves the provincial capital with domestic connections to Buenos Aires and other Argentine cities. Verify current routes and schedules with airlines directly, as services change.
By Bus
Long-distance buses connect Posadas and Puerto Iguazú with Buenos Aires (roughly 10–16 hours depending on route and stops) and other major Argentine cities. The provincial bus network also links smaller towns such as Oberá, Eldorado, and San Ignacio. Intercity bus travel in Argentina is generally comfortable, with semi-cama and cama (reclining and flat-bed) options available on overnight routes.
By Road
Ruta Nacional 12 runs along the Paraná River, connecting Posadas northward to Puerto Iguazú and passing through key towns and Jesuit mission sites. Driving is a practical way to explore the province at your own pace, but road conditions can vary; check local advisories before setting out.
Crossing into Brazil or Paraguay
Puerto Iguazú has official border crossings into Foz do Iguaçu (Brazil) and Ciudad del Este (Paraguay). Carry your passport and verify current border requirements before crossing, as immigration rules and processing times can shift.
Getting Around
Local buses (colectivos) serve routes between most towns and are the most affordable way to get around within the province. Taxis and remises (private hire cars) are available in Posadas and Puerto Iguazú; in smaller towns, remises are often the most reliable option and are typically booked by phone.
Renting a car offers the most flexibility for reaching mission ruins, waterfalls, and rural mate plantations that are difficult to access by public transport. Road signage is generally adequate along the main routes. Fuel stations are concentrated in larger towns, so fill up before long rural stretches.
Within Iguazú National Park, a free train (the Tren Ecológico de la Selva) links the visitor center with the trail circuits on the Argentine side, making it easy to explore the park without your own vehicle.
Things to See & Do
Iguazú Falls
The defining attraction of the province—and one of the world's great natural spectacles—Iguazú Falls straddles the Argentina–Brazil border. The Argentine side (Parque Nacional Iguazú) offers extensive trail networks that bring visitors to walkways directly above the cascades, including the iconic Garganta del Diablo (Devil's Throat). Admission fees and opening hours are set by Argentina's national parks authority (Administración de Parques Nacionales); verify current rates on their official site or on arrival.
Jesuit Mission Ruins
- San Ignacio Miní – The best-preserved Jesuit reducción in Argentina, a UNESCO World Heritage Site located near the town of San Ignacio. The carved sandstone facades give a powerful sense of the settlement's former scale.
- Santa Ana and Loreto – Two further ruined missions accessible along Ruta 12, less visited and atmospheric in a different way.
- Santa María la Mayor – In the southern part of the province; a quieter site worth visiting for those with a deep interest in the Jesuit heritage.
Yerba Mate Plantation Tours
Several producers around Oberá and other rural areas offer guided visits to understand how yerba mate is cultivated, harvested, and processed. Ask locally for current operators, as offerings change.
Wildlife and Ecotourism
The province contains portions of the Atlantic Forest, one of the world's most biodiverse and threatened ecosystems. Toucans, tapirs, howler monkeys, and giant otters can be spotted in and around the national park and in private reserves. Reputable naturalist guides are available through the park and local operators in Puerto Iguazú.
Posadas City
The provincial capital is a pleasant river city with a pedestrian waterfront (costanera), a central market, and a short ferry link to Encarnación in Paraguay. The Jesuit Block museum (verify local name and hours) traces the regional mission history.
Food & Drink
Yerba Mate
Mate is not just a drink here—it is a social ritual. Sharing a gourd of mate is a gesture of hospitality throughout the province. Visitors are often welcome to join in; accept the gourd with both hands and drink fully before returning it.
Regional Cuisine
The food of Misiones reflects its mixed Guaraní, immigrant European (German, Polish, Ukrainian, Italian), and broader Argentine roots:
- Locro: A hearty stew of corn, beans, and meat, particularly common in cooler months.
- Chipá: Cheese-and-cassava bread rolls, Guaraní in origin, sold at roadside stalls and markets throughout the province.
- Asado: Argentine barbecue is ubiquitous; quality beef is available in restaurants and at family gatherings.
- River fish: Surubí and dorado feature on many menus in riverside towns, grilled or baked simply.
Drinking
In addition to mate, tereré (cold mate with herbs) is popular in summer. Local craft beer has grown in small towns. Argentine wine (though not produced locally) is widely available.
Practical Information
Emergency Contacts
For all emergencies in Argentina, the general emergency number is 911. Fire services: 100. Medical emergencies: 107. Police: 101. Verify locally whether these numbers are operative in the specific area you are visiting.
Connectivity
Mobile coverage from major Argentine carriers is available in Posadas, Puerto Iguazú, and larger towns. Coverage can be patchy in rural and forested areas. Wi-Fi is available in hotels and many cafés in larger towns.
Money
ATMs are available in Posadas, Puerto Iguazú, and larger towns. Confirm with your bank that your card will work in Argentina before departing. Smaller villages may operate largely on cash.
Accessibility
Iguazú National Park has made efforts to improve accessibility, with paved walkways on some circuits. San Ignacio Miní has uneven terrain. Travelers with mobility requirements should verify current conditions directly with each attraction.
Time Zone
The province observes Argentina Standard Time (ART, UTC−3). Argentina does not observe daylight saving time.
Safety
The province of Misiones is considered one of the safer regions of northeastern Argentina for travelers. Standard precautions apply: keep an eye on belongings in busy markets and bus terminals, avoid displaying expensive electronics unnecessarily, and use registered taxis or remises rather than unmarked vehicles.
In and around Iguazú National Park, stay on marked trails. The walkways above the falls involve height and can be slippery when wet; follow park staff instructions. The jungle environment means encounters with insects and, occasionally, wildlife—respect any distance guidelines posted in the park.
Border areas around Puerto Iguazú (the tri-border with Brazil and Paraguay) see high commercial activity. Exercise normal urban awareness in this area. Consult your government's official travel advisory for up-to-date assessments before departure.
Local Culture & Etiquette
Guaraní culture is foundational to the province's identity. The Guaraní language is still spoken by many residents, and Guaraní words permeate everyday Argentine Spanish in the region—you will hear them in place names, food terms, and casual conversation. Several indigenous communities continue traditional practices; visitors should approach any community visit with respect and preferably through a locally arranged, community-endorsed guide.
The Jesuit missions of the 17th and 18th centuries left a lasting imprint. The synthesis of European Baroque art with Guaraní craftsmanship produced a distinctive visual tradition visible in the carved stone of the ruined churches. Local museums and interpretation centers at the mission sites provide historical context.
The province also has a significant community of descendants of European immigrants—particularly German, Polish, Ukrainian, and Italian settlers who arrived in the late 19th and early 20th centuries. Towns like Oberá celebrate this multicultural heritage with an annual festival (Fiesta Nacional del Inmigrante); verify dates locally before planning around it.
