I've been to Iguazú Falls countless times. Seeing them under a full moon was something else.

The author went on a full-moon walk at Iguazú Falls at night.

Courtesy of the author My husband and I booked a nighttime tour of Iguazú Falls during the full moon.

We walked through the forest in darkness, listening to wildlife and rushing water.

The moonlit waterfalls were unlike anything I'd seen during my many daytime visits.

I'm originally from Argentina and grew up in Brazil, so I've been to the Iguazú Falls — which sit between the two countries — plenty of times.

This year, I decided to take my husband and kids to see the world's largest waterfall system , since they had never been before.

And while their minds were blown during our daytime visit, it was the night walk I took with my husband through the falls that, honestly, took my breath away.

The full moon tour is small and private The night tour is only available during a full moon , and you can choose different time slots.

We were there with friends for a wedding and chose the 9:25 p.m. slot to guarantee it'd be really dark out.

While kids are allowed on the full-moon tour, we decided to leave ours at the hotel with my mom so we could fully enjoy the experience.

The author walked in the dark through the Iguazú Falls.

Courtesy of the author Our tour had 120 people, which is relatively small compared to the thousands you can encounter walking along the metal walkway leading to the falls during the day.

The experience felt intimate because we were such a small group, which gave us space and time at every stop.

The walk starts right before the falls, with a small performance by the Guaraní, the indigenous people of that part of Argentina .
