The name 'Moconá' originates from the Guaraní language, meaning 'to swallow everything'.
The falls are created by a geological fault line rather than a typical river obstruction.
The falls can temporarily disappear entirely if the Uruguay River level rises enough to submerge the basalt ridge.
The site sits on the international border between Argentina and Brazil.
The Yabotí Biosphere Reserve, which contains the falls, covers over 250,000 hectares.
The Moconá Falls are a series of longitudinal waterfalls spanning 3 kilometers along the Uruguay River, formed by a geological fault line. Unlike typical vertical cascades, these falls run parallel to the river's flow, creating a deep canyon effect. The height of the falls varies significantly based on the water level of the Uruguay River, which fluctuates due to upstream dam operations and rainfall. They are situated within the Yabotí Biosphere Reserve, a protected area of the Paranaense rainforest. Access to the falls is primarily facilitated through boat excursions that navigate the river channel adjacent to the rock formations. The geological structure consists of basaltic rock, which creates the unique lengthwise split in the river. The region is known for its high biodiversity and subtropical vegetation.

Check the official river level status before traveling, as high water frequently closes boat operations.
Carry insect repellent and high-SPF sunscreen, as the area has high humidity and limited shade on the water.
Bring a waterproof bag or case to protect camera and phone equipment from river spray during boat trips.
Attempting the trip without verifying the current water level status on the official website; if the river is high, the falls are not visible.
Access is subject to daily river conditions; the park may close at short notice due to heavy rainfall or high water levels.
Maintain silence to observe local wildlife and strictly follow park ranger instructions regarding boat safety and life jackets.
