This is a place full of enigmas, set on a very high plateau, dominated by the stunning view over Lima's valleys. It is famous for its huge rocks with amazing shapes formed over thousands of years, naturally sculptured into human and animal shapes (camels, frogs, lions, condors, turtles). 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.
By land: Lima-Chosica by the Carretera Central (Central Road) followed by the road to San Pedro de Casta (89 km -55 miles- north-east of Lima). From here, the top is reached on foot (2 hours) or riding an animal.
