What to pack for Iguazu Falls

Direct answer: The essentials are a rain cover or poncho, closed shoes with good grip, sunscreen, insect repellent, water and a plastic bag or waterproof case for your phone. The boardwalk soaks you even on a sunny day, and when the river runs high the spray gets far denser. Bring a valid travel document if you are crossing the border, and a change of clothes if you are doing a boat trip, because it soaks you completely.

The essentials, and why

• Rain cover or poncho. Not for rain: for the spray off the falls. An umbrella gets in the way, because you need both hands and the wind turns it inside out.
• Closed shoes with good grip. These are kilometres of permanently wet boardwalk. Flip-flops are the most common mistake.
• Sunscreen. Much of the route is in the open, and the water reflects.
• Insect repellent. This is Atlantic rainforest.
• Water. The Brazilian trail runs 1.2 km; the Argentine side needs a full day.
• A plastic bag or waterproof case for your phone and camera. The spray gets into everything.

What changes when the river runs high

When the flow rises, the experience genuinely changes: the spray on the boardwalks becomes far denser, the noise grows and your clothes soak in a way they do not at normal flow. In a strong flood, the spray itself hides part of the view.

By season

• October to March: strong heat, above 35 °C. Light clothing, a hat and more water than you think.
• June to August: mild days and cold nights. Bring a jacket for late afternoon.

For the boat trip

The Macuco Safari and Gran Aventura soak you completely, and that is not an exaggeration. Bring a change of clothes and leave electronics somewhere dry. The boats provide a dry bag, but the rest of you comes back drenched.

What NOT to bring

• A drone. Banned in both national parks, and bringing one exposes you to seizure: see can I fly a drone at Iguazu Falls?
• Food in your hand. Coatis approach and may scratch or bite trying to grab it. Feeding wildlife is an environmental offence. Keep snacks inside a closed bag.
• Large luggage. The Brazilian park has paid lockers, but sorting it out beforehand is simpler: see lockers, wi-fi and restrooms.

Documents

For the Brazilian side, photo ID is enough. To cross the border you need a valid travel document for your nationality: see do you need a passport for Puerto Iguazú.
