This is the moment a secret cave hidden behind a waterfall is discovered by a tourist visiting the beautiful attraction near Rio de Janeiro.
The group make their way up to the ‘Pedra Que Engole’ (rock that swallows) and find they can slide right underneath the falls.
Taking his GoPro camera with him the man films his passage through a dark and unnerving path that emerges around the side of the waterfall.
The video is filmed near the Trindade Village in Brazil, where after a short hike the waterfall can be reached.
At the start of the video a group are seen swimming around in the surrounding pools.
A man in the party then notices that there may be a hidden passageway under the rocks.
