Public buses connect major cities (Posadas, Puerto Iguazú, Oberá) frequently and affordably. In Puerto Iguazú, local buses run to Iguazú Falls National Park entrance. Taxis and remises (private cars) are available in cities; negotiate fares beforehand or use meters. Ride-hailing apps like Uber operate in Posadas and Puerto Iguazú. Car rentals are useful for exploring Jesuit Missions and rural areas; major agencies are at Posadas and Puerto Iguazú airports. Roads are generally paved but can be narrow; GPS coverage is spotty in jungle areas. Boat tours operate on the Paraná and Iguazú rivers. For the Argentine side of the falls, use the Ecological Jungle Train within the park.
April to June and August to October. These periods offer pleasant temperatures (15-25°C/59-77°F), lower humidity, and fewer mosquitoes. The falls are most powerful from December to March (rainy season) but it's hot and humid. July brings cooler weather but more tourists during South American winter holidays. Avoid peak summer (January-February) due to extreme heat, heavy rains, and crowds. September is ideal for the National Flower Festival in Oberá.
Mate culture is central—sharing the bitter herbal tea is a social ritual. If offered mate, accept it (rejecting is rude); drink the entire gourd and return it to the host. Casual dress is acceptable, but cover up when visiting churches or indigenous communities. Tipping 10% is customary in restaurants if service isn't included; round up taxi fares. Greetings involve a kiss on the cheek (even between men and women). Respect Jesuit Mission ruins—don't climb on structures. In Guarani communities, ask permission before photographing people. Lunch is the main meal, often followed by a siesta; many businesses close 12-4 PM.
Misiones is generally safe for tourists, especially in popular areas like Puerto Iguazú and the Jesuit Mission circuit. Exercise normal precautions: don't display valuables, use hotel safes, and avoid isolated areas at night. In Puerto Iguazú, be cautious near the Tres Fronteras landmark after dark. Petty theft can occur on crowded buses and in tourist areas—keep bags secure. When visiting waterfalls, stay on marked paths as rocks can be slippery. Border areas with Paraguay and Brazil have increased smuggling activity; avoid unofficial crossings. Common scams include overcharging taxis (use radio taxis or apps) and fake tour operators—book through reputable agencies. Road safety is a concern; drive cautiously on rural routes, especially at night.
Misiones is a subtropical region with risks of mosquito-borne diseases. Dengue fever is common, especially during rainy seasons (October-May). Use EPA-registered insect repellent, wear long sleeves/pants, and sleep under mosquito nets. Yellow Fever vaccination is recommended if traveling from endemic areas; consult a travel clinic 4-6 weeks before your trip. Tap water is generally safe in cities like Posadas and Puerto Iguazú, but bottled water is advised in rural areas. Public hospitals exist in major cities (Hospital Madariaga in Posadas, Hospital de Puerto Iguazú), with private clinics offering better facilities. Travel insurance with medical evacuation coverage is strongly recommended.
