Learn about the Itaipu Hydroelectric Dam during a 6-hour educational tour and catamaran ride. With your local guide, tour the dam, including the observation deck and the spillway, or opt to upgrade the tour to include a tour inside the facilities (additional expense). Board a catamaran to sail out on Itaipu Lake to get a panoramic perspective of the dam, which spans 5 miles (8km) of waterfront between Brazil and Paraguay. Learn about the dam's role in providing power for both countries, as well as its local provisions for protecting wildlife. Round-trip transportation from both Foz do Iguaçu and Puerto Iguazu is included.
