On 12 October 2026, a park in Argentina closed the walkways at Iguazu Falls. There was a big flood after very heavy rain. More than 12,000 cubic metres of water went over the falls every second. The heavy rain came with El Niño. El Niño means the Pacific Ocean becomes warmer than usual.
The falls are on the border between Argentina and Brazil. They are the biggest group of waterfalls in the world. The river falls over hard rock from very old lava. There are 150 to 300 waterfalls. The number changes with the water level.
The water level can change a lot. Usually, about 1,746 cubic metres go over the falls every second. But in 2006, there was very little rain for a long time. Then only 300 cubic metres went over every second. The forest around the falls is home to many birds and monkeys.
