A lunar rainbow, or moonbow, occurs when moonlight is refracted through the mist of the waterfalls, typically appearing colorless to the human eye due to low light levels.
The tour uses the train tracks that connect the Central Station to the Garganta del Diablo station, which are otherwise inaccessible to the public after dark.
The Iguazú National Park is home to over 2,000 plant species and hundreds of bird species, some of which are only active or audible during the night.
The volume of water plummeting over the Garganta del Diablo is consistent regardless of time, but the sound intensity often seems higher due to the absence of daytime visitor chatter.
The park maintains a strict 'no flash' photography policy to protect the nocturnal animals living in the surrounding subtropical rainforest.
Paseos de Luna Llena en las Cataratas del Iguazú offers exclusive nocturnal access to the Garganta del Diablo waterfall within the Iguazú National Park. The tour is conducted only during the five nights surrounding the full moon each month. Visitors are transported via the Ecological Jungle Train to the station located near the main waterfall. The experience centers on observing the lunar rainbow, or moonbow, created by the mist of the falls under moonlight. The tour is guided by park rangers who provide information on the local ecosystem and nocturnal wildlife. Participants remain on elevated walkways throughout the duration of the visit. The capacity for these evening walks is strictly limited to ensure minimal environmental impact. The site is located in the Misiones province of Argentina within a UNESCO World Heritage site.

Bring a high-quality tripod, as long-exposure photography is necessary to capture the falls in low light without using a flash.
Dress in layers; the jungle humidity drops significantly after sunset, and the mist from the falls can be cold.
Book well in advance through the official park concessionaire, as these limited-capacity tours sell out months ahead.
Do not attempt to walk to the observation platforms outside of the official guided group; never use a flashlight or camera flash on the wildlife.
Operations are strictly limited to the five days surrounding each full moon; subject to cancellation based on weather conditions or water levels.
Maintain silence to observe wildlife; stay strictly on designated walkways; use of camera flashes is prohibited.
