Today, July 16th, is the main day of the Festivity of the Virgen del Carmen in Pisaq as well as in other cities of Cusco like Paucartambo, Checacupe and Huarocondo.
Actually, the feast goes from the 15th to the 18th. One remarkable thing, in addition to the devotion, the food (it seems the main dish is pig as you can see in the picture below), and beer galore, is to see a different view of Pisaq. During the four days the main square and some streets in Pisaq are without handicraft stands so you can admire the beautiful pisonay tree and the quietness of this city in the Sacred Valley.
