I'm Argentinian, I live in the city of Villa Maria (Cordoba province). I made a 7 day trip to visit the stunning waterfall, which is 771 metres high. The place is surrounded by mountain ranges. While access is not easy, the effort is well worth it because the scenery is absoloutely fantastic and the people that you meet are so friendly. A road crosses the dense jungle, swamps and several rivers. It is advisable to go with a guide and let them lead the way. See my pictures of this beautiful place.
