Is Iguazu Falls safe? An honest guide for visitors
Short answer
Iguazú is safe for visitors, with well-run parks and relaxed border towns. The realistic risks are heat, slippery walkways, wildlife such as coatis, and petty crime in Foz do Iguaçu. Most visitors have no problems.
The real risks
Coatis
These racoon-like animals snatch food and can bite or scratch. Never feed them and keep food sealed in bags.
Heat and humidity
Summer temperatures reach 31–32°C with high humidity. Drink plenty of water, wear a hat and take breaks in the shade.
Slippery walkways
Spray makes walkways and steps wet; wear shoes or sandals with grip.
Petty crime in Foz
Foz do Iguaçu is a bigger city with more petty theft; keep valuables out of sight and use taxis at night.
Areas and times to take care
Puerto Iguazú is small and relaxed, comfortable to walk at night. Foz do Iguaçu on the Brazilian side has a busy centre and some areas with more crime; use taxis after dark. The border towns of the Triple Frontier with Paraguay (Ciudad del Este) are busy and need extra care with bags.
Getting around safely
Public buses run between Puerto Iguazú and the Argentine park and across the border to the Brazilian park. Remises (private cars) and taxis are licensed and easy to find. Uber works in Foz do Iguaçu.
Solo and women travellers
Iguazú is comfortable for solo women. The parks are busy, Puerto Iguazú is relaxed, and hostels are well run. Use taxis at night in Foz do Iguaçu.
Health, water and heat
Tap water in Puerto Iguazú is generally considered safe, but many travellers drink bottled water. Dengue occurs in the region, especially in summer; use repellent. Yellow fever vaccination may be recommended for Misiones and the Brazilian side; check with a travel clinic. Sun protection is essential.
