South America's great engineering marvel is the world's largest hydroelectric facility, and spans the Paraná river between Paraguay and Brazil. Construction on the dam, as tall as a 65-story building, was completed in 1984. The installation supplies 19% of Brazil's power needs and an astounding 91% of Paraguay's. Admission is free from the Paraguayan side. (The visitor center on Brazil's side charges for visits.) Take in an informative 90-minute tour and/or a spectacular
sound-and-light show on weekend nights.
