Willcahuaín is an archaeological site located 7 km North of Huaraz City. They were built by the members of the Wari culture about 600-800 years A.D. According to history, they used to house mummies of the Wari culture. The construction consists of a roof of large stone slabs and an extensive ventilation system. Due to the good ventilation, the site remains in a very well preserved state. From the ruins we continue our hike towards Monterrey where we have the opportunity to visit the very relaxing Thermal Springs named after the village. From there, we take a taxi or minibus back to Huaraz. The whole trip takes 5 to 6 hours.
