Yucumã Falls, also known as Moconá Falls, is a dramatic waterfall located on the Uruguay River on the border between the province of Misiones, Argentina, and the state of Rio Grande do Sul, Brazil. It is the second widest waterfall in the world, after the Iguazu Falls.

The Yucumã Falls are a series of 275 individual waterfalls that stretch for 1.8 kilometers. The falls are up to 80 meters high and 1.5 kilometers wide at their widest point. The average flow rate of the falls is 6,000 cubic meters per second.

The Yucumã Falls were formed by a process called river capture. River capture occurs when a river diverts the flow of another river. In the case of the Yucumã Falls, the Uruguay River captured the flow of the Peperi Guazú River.

The Yucumã Falls are best viewed from the Brazilian side. There is a viewing platform located at the Turvo State Park, which is about a 15-minute drive from the town of Derrubadas. Visitors can also take a boat tour on the Uruguay River to get a closer look at the falls.

The Yucumã Falls are home to a variety of wildlife, including jaguars, caimans, and monkeys. The falls are also a popular destination for birdwatchers, as over 400 species of birds have been recorded in the area.

The Yucumã Falls are still actively being formed. The Uruguay River is continuing to erode the bedrock, making the waterfall taller and wider. The Peperi Guazú River is also being eroded, and it is slowly being diverted further away from the waterfall.
