This is a place full of mystery; Marcahuasi is on a very high plateau, from which it is possible to look out over the beautiful panorama of the valleys surrounding Lima. It is famous for its enormous rocks, which have been modeled by natural forces such as the wind, rain and temperature over thousands of years and have assumed remarkable forms, including anthropomorphic and zoomorphic figures (camels, frogs, lions, condors, tortoises). The most important rocks are the Amphitheater, the Labyrinth and the Monument to Humanity which, many say, has the profile of all five human races on Earth. Some say that it is a good place for UFO sighting. Without doubt, this place has high levels of energy due to its volcanic origins. Similar to the Australian monolith of Uluru, this sacred mountain is one of the most important energy centers in the world. Since remote times locals have come up to this plateau to worship their gods.
In addition, it is surrounded by stunning scenery and lagoons, and fauna that only lives in these high regions. The area is perfect for bird watching.
