The latest resort to open in Peru’s magical Sacred Valley, located close to the Inca capital Cusco, is the explora Valle Sagrado. The property has been built on ancient corn plantations, and during its construction, archaeological studies revealed many vestigial Inca remains, some of which required the architect’s plans to be revised. At the end of an Inca platform stands the Casa de Baños Pumacahua, a 17th-century hacienda that once belonged to Peruvian independence hero Mateo Pumacahua. This has now been turned into a unique spa, with restored colonial frescoes and 400-year-old walls. After treatments, guests may swim in a heated outdoor pool with views of the Andes.
