Ciudad del Este is Paraguay's second-largest city and a famous shopping hub near the borders with Brazil and Argentina. It sits close to the mighty Parana River and the enormous Itaipu Dam.
You can cross the Friendship Bridge, marvel at the giant Itaipu Dam that makes electricity for millions, and take a short trip to see waterfalls nearby. The busy streets are packed with shops selling everything you can imagine.
The Itaipu Dam has a wildlife park and a nature area where you might spot birds, monkeys, and other animals living near the great river.
Itaipu is one of the largest dams in the world, and tours let you see the giant machines that turn river water into power.
