The system used metal halide lamps installed in the early 2000s, and manufacturers discontinued the high-power models. Without replacement parts, maintenance was no longer viable. They are switching to LEDs.

When does it come back?

It is expected in 2027. After reopening, Itaipu's tourism division intends to expand from two to four or five sessions a week.

What changes with the LEDs?

Peter Gasper's original 1997 design is preserved, with the same 829 light points. What changes is that colour and intensity are controlled from a digital panel, with no manual lamp changes.

What can I do at night in Foz instead?

The Marco das Três Fronteiras runs Tuesday to Sunday from 2pm to 9pm, with sunset and early-evening performances. There is also dinner in Puerto Iguazú and the Dreams Park Show, open until 10pm.

Itaipu Illuminated in 2026: paused until 2027, and what to do instead

Is Itaipu Illuminated running? The pause until 2027

The last show was on 8 August 2026. The dam is being relit with LEDs, and the tour should return in 2027

It is not. The last show was on 8 August 2026, and the tour was paused for the lighting system to be modernised. It is expected back in 2027.

Direct answer: It is not running. The last Itaipu Illuminated show was on 8 August 2026. The tour was paused for the modernisation of the dam's lighting, replacing metal halide lamps with LEDs, and it is expected back in 2027. If you have seen the attraction listed on a ticket table, confirm directly with Turismo Itaipu before building it into your plans.

Why it stopped

The show lit the dam for almost 24 years. The system relied on metal halide lamps installed in the early 2000s, and manufacturers discontinued the high-power models used. Without replacement parts, maintenance was no longer viable.

It was not for lack of demand: in the first months of 2026 the attraction drew more than 13,500 visitors, and since 2007 it has totalled 486,041.

What changes when it returns

The modernisation preserves the original design, created by designer Peter Gasper in 1997 and inaugurated on 14 November 2002. You will recognise the same frame of light across the dam.

What changes is the technology:

829 light points retained, preserving the design
Colour and intensity controlled from a digital panel, with no manual lamp changes
Similar technology to that used on structures such as the Empire State Building and Notre-Dame Cathedral

And there is a promise that matters to travellers: the show ran only Fridays and Saturdays. After reopening, Itaipu's tourism division intends to expand to four or five days a week.

What is still running at Itaipu

The pause affects only the night tour. The complex remains open:

Tour	Price	When
Itaipu Panorâmica	R$63	Daily, 8:30am to 4pm
Itaipu Special (inside the dam)	R$185	Daily, limited places
Biological Refuge	R$48	Wednesday to Monday, limited places
Ecomuseum	free	Wednesday to Monday, 8:30am to 4pm

The best timing for each is in Itaipu: the best time to visit without queuing.

What to do at night instead

Marco das Três Fronteiras, open Tuesday to Sunday from 2pm to 9pm, with sunset over the meeting of the rivers and performances in the early evening (hours and prices)
Dinner in Puerto Iguazú, crossing the bridge in the late afternoon
Dreams Park Show, on Avenida das Cataratas, open until 10pm

Before you go

This page is dated: when the attraction returns, days and times will change. Confirm on the official Turismo Itaipu site before planning.
