Moconá Waterfalls

Moconá Waterfalls are a series of falls that run for three kilometers along the Uruguay River in Misiones Province, Argentina, where water drops between five and seven meters into a parallel canyon. The main flow occurs within a long fault in the riverbed, with the water level on either side of the crack differing in height.

The falls formed during the Ice Age when geological shifts created a submerged canyon in the riverbed that reaches depths up to 100 meters. European explorers mapped the region in the 20th century, bringing the falls to wider attention.

The indigenous Guaraní people named these falls Moconá, which translates to 'that which swallows everything' in their native language. This name refers to the powerful current that draws water into the submerged canyon along the riverbed.

Visitors can reach the falls only through boat tours that depart from the park dock and last about 90 minutes. Water levels vary depending on the season, so the falls are sometimes fully visible and other times concealed by the river.

Unlike conventional waterfalls that flow downward, the falls run parallel to the river course, creating a longitudinal water cascade. The falls are fully visible only when water levels are low, making them a weather-dependent natural phenomenon.
