When you finally arrive in Chavín de Huantar, you expect to enter and observe the ruins but subtly take you to a restaurant next to the ruins for lunch. Finally, around three in the afternoon you enter the Chavin complex and an interesting two-hour visit is made. I think it's more than enough time to visit the place.
It is a monument designated a World Heritage Site by Unesco.
Chavín de Huantar is a fortress-shaped temple built around 800 BC. and it is the only legacy that has come to us from the Chavín culture.
There is an interesting maze of galleries inside which was played with the riverbed to create sounds that frightened the pilgrims who came.
The Chavin culture used the hallucinogenic effects of the San Pedro cactus, also called peyote.
There is another way to reach Chavín de Huantar and this is through a three-day walk from the town of Olleros to Chavín through unexplored pre-Inca ruins.
