Itaipu is a binational project of Brazil and Paraguay, and its scale is the point. The Paraná River is held back by a long concrete and earth dam, creating a reservoir that stretches far upstream, and twenty generating units inside the powerhouse supply a large share of both countries' electricity. Visitors take the panoramic tour by bus from the visitor center, with stops at viewpoints over the main dam, the spillway and the powerhouse area, and a short film or exhibit explains how the project was built in the 1970s and 1980s. A more in-depth special tour, with access to inner areas, has stricter requirements and limited availability. The surrounding grounds include a refuge, an ecomuseum and a night illumination show on selected evenings. Expect security checks, a passport or ID requirement, and a surprisingly gentle pace, with the guide's commentary focused on engineering, history and the environmental legacy of the project.
Practical details matter more here than at the falls. The panoramic tour typically lasts about an hour and ten minutes once you are on the bus, but the whole visit can take two to three hours with check-in, the film and the shuttle between stops. Bring your passport or other official photo ID, because Itaipu is a secure facility, and wear closed shoes and modest clothing. Cameras are fine at the designated viewpoints, but follow the guide's rules about where photography is allowed.
The Viator listing linked here is a small-group tour that includes the Itaipu entrance, which makes it a convenient way to see the dam if you are staying in either town; hotel pickup options vary, so read the inclusions. Some reviewers on other listings mention paying the entrance fee separately on the spot, so confirm what is included before booking. Opening hours and tour types are set by the operator, and some days or times have restricted access, so book ahead in the busy school holidays and check the schedule in November.
Itaipu is rarely the headline of a trip to the falls, but it suits several kinds of traveler. Engineering enthusiasts will love the scale, families can enjoy the viewpoints, and anyone caught by a wet forecast gets a dry-ish alternative. If you have only a day or two in the area, put the falls first and fit the dam into a spare half day. A combination with the bird park or a Paraguayan shopping stop is common on organized tours, but you will move faster and more comfortably if you separate them.
