Itaipu Dam, a binational project between Paraguay and Brazil, offers a fascinating glimpse into engineering and hydroelectric power generation. Guided tours are available and highly recommended to fully understand the dam's operations and history; solo exploration is possible but less informative. Accessibility is generally good, with facilities for visitors with disabilities. The dam operates year-round, but specific tours might have seasonal schedules, so checking in advance is advisable. Expect to spend around 3-4 hours for a comprehensive visit. The cost varies depending on the tour selected, ranging from free to moderate pricing. Consider booking tours in advance, especially during peak tourist season.
