Dangers & Annoyances

River currents are strong and swift; tourists have been swept downriver and drowned. Of course, don’t get too close to the falls proper.

Heat and humidity are often intense and there’s plenty of hungry insect life, so pack sunscreen and repellent. Take your own water.

On both sides, you’ll encounter coatis. Keep food well away from them; though these clownish omnivores seem tame, they become aggressive around food and will bite and scratch to rob you of it. Both parks have medical points in case of coati attack.

You are likely to get soaked, or at least very damp, from the spray at the falls, so keep documents and cameras protected in plastic bags. You can buy plastic ponchos on both sides.

Stamps for sale on the Argentine side of the park cannot be posted anywhere but in the park itself or large cities.
