If you’re visiting Foz do Iguaçu and want to see what one of the world’s largest hydroelectric dams looks like after sunset, the Itaipu Iluminated tour might just be your best bet. Priced at around $37 per person, this 2-hour experience combines a fascinating glimpse into engineering marvels with a dazzling display of dynamic lighting that transforms the dam into a luminous masterpiece. With pickup offered and a guided tour, it’s easy to see why this activity is booked about 49 days in advance on average — the word is spreading for good reason.
What we love most about this tour is its unique lighting display, which is quite unlike anything else worldwide.

Plus, the tour’s professional guides ensure you learn about the dam’s history and engineering, adding depth to the spectacle.
However, a quick consideration: the language barrier might be noticeable, as reviews mention that the driver speaks mainly Portuguese, with limited English. For travelers who don’t mind a bit of language immersion, this isn’t a deal-breaker, but it’s something to keep in mind.

The illumination of the Itaipu Dam is arguably the highlight. The dynamic lighting system creates a vibrant spectacle, transforming the gray concrete into a kaleidoscope of colors and patterns. This is a truly unique experience—the only one of its kind in the world, according to the tour description. The lights dance across the dam’s surface, emphasizing its architectural differences and creating a stunning contrast against the night sky.
