One of the most important things to know is that Iguazu Falls straddles the border between Argentina and Brazil.
If you’re visiting the falls from the Brazilian capital of Rio de Janeiro, then brace yourself for a pretty long journey, as they’re roughly 1,500 kilometers (932 miles) apart.
The Brazilian side offers the best overall view of the Iguazu Falls and is amazing for taking photos, but on the Argentinian side, you can get much closer to the waterfalls themselves.
The Brazilian side of the falls is generally cheaper than the Argentinian side. For non-Brazilian nationals, the entrance ticket costs roughly $20 USD when you’re arriving from Foz do Iguaçu. On the Argentinian side, it costs $30 USD per ticket.
April and May have the best balance between good weather, high water flow, comfortable temperatures, and relatively few crowds.
On the Argentine side, Iguazu Falls are open from 8 am to 6 pm daily, with the last entry at 4:30 pm.
A jet boat is an amazing and adventurous way to experience Iguazu Falls. This is a thrilling ride that takes you through the rapids and even under the cascading water.
