literally hidden within rio de janeiro's geographical wealth are a number of lesser-known landmarks, which offer visitors some unique sights. one such gem is the gruta do ouvido cave, hidden in the great expanse of the tijuca national park, stirring great inspiration for all that visit it.

'gruta do ouvido' can be translated as the 'cave of the hearing', and may well be called this due to its position - hanging from one of the cliffs in the park, it allows listening to all the energy and sounds of the city and of the ocean.
