Full Moon Walk at Iguazu Falls: what's running in 2026

Direct answer: The Full Moon Walk is still on the official calendar of the Argentine side, but its destination changed: with the Devil's Throat closed since August 3, 2026, the night walk now ends at the Upper Circuit viewpoints. The next nights are October 22 to 26, November 20 to 24 and December 19 to 23.

What changed in 2026

For years, the full moon walk meant the Devil's Throat: a train ride to the last station and a walk along the catwalk to the platform over the falls. That is not the case right now. The Devil's Throat has been closed since August 3, when the park preventively removed the catwalks because of the flood, and there is no reopening date (see is the Devil's Throat open?).

The official page of the park concessionaire, Iguazú Argentina, now describes a different route: the train runs from Estación Central to Estación Cataratas, and the walk continues along the catwalks over the upper Iguazú River to the Upper Circuit viewpoints, lit only by the moon. A lot of content online, including articles from October, still repeats the old Devil's Throat route. When you book, go by the official site.

How it works, per the official source

• When: five nights a month, around the full moon. The concessionaire's 2026 calendar lists October 22 to 26, November 20 to 24 and December 19 to 23.
• Time slots: three per night, with check-in at the park entrance at 7:45 p.m., 8:30 p.m. and 9:15 p.m.
• Length: about 2 hours and 30 minutes.
• What's included: night entry, a guide in Spanish and English, and the Rainforest Ecological Train. Dinner and daytime park admission are not included, and a regular park ticket does not cover the walk.
• Price: AR$ 95,000 per adult, AR$ 47,500 for ages 6 to 12, free for kids 5 and under. The concessionaire says there are no discounts for this activity.
• Tickets: sold on the official site, between 30 and 90 days before each date. Spots are limited.
• Accessibility: the route is listed as fully accessible, with free wheelchairs (you need a companion to push).

If you arrive early, you can check in and wait in the services area, which has places to eat. The trails close around 4 and 5 p.m., so you can't explore the park while you wait. On walk nights, the bus company Río Uruguay runs a special service from the Puerto Iguazú bus terminal, marked with a "Cataratas" sign.

The October flood and the risk of cancellation

October 2026 brought the highest flow in the series Guia 3 tracks: the Iguazú River reached about 15,800 m³/s on October 14. The Upper and Lower circuits on the Argentine side closed between October 12 and 14, and the Upper Circuit reopened on October 15, according to the Misiones press. Since the full moon walk depends on the Upper Circuit, another rise in the river can cancel a night.

The concessionaire says that if a walk is canceled for weather or safety reasons, it notifies you by email and offers a new date or a refund. Before you leave the hotel, check the live flow on Iguazu Falls today and the status of each side on are Iguazu Falls open today?.

Moonbows: a chance, not a promise

A moonbow is a rainbow made by moonlight hitting the mist of the falls. It needs three things at once: a full or nearly full moon, a clear sky and plenty of mist. Even then, to the naked eye the arc usually looks whitish, and the colors show up better in long-exposure photos.

A high river means more mist, which helps. Clouds kill the chance. Our rainbows at the Falls page estimates the odds for each side and includes a full moon calendar. According to the ephemeris, the moon is full in the early hours of October 26, on November 24, on the night of December 23 and on January 22, 2027. The concessionaire has not yet published walk dates for 2027.

What about the Brazilian side?

Iguaçu National Park in Brazil currently has no official full moon walk of its own. The Brazilian concessionaire's site offers Céu das Cataratas, a stargazing activity on Saturdays, with 20 spots per session, combining sky watching and Guarani knowledge. It's a different idea: the focus is the starry sky, not the full moon. The old "Noite nas Cataratas", with dinner at the Porto Canoas restaurant, still shows up on older pages, but the restaurant is closed for renovation and we found no schedule for that tour in 2026.
