Mysticism & archeology
If you have a day to spend somewhere in the Sacred Valley, and want to see more than archeological sites, Pisac is your spot. Read my article article about why Pisac is a great alternative to Machu Picchu, though most people do both.
Pisac is best known for the Pisac archeological site that can visit by guided tour, though in group tours you often only get one hour at the site. If you want to see all of the Pisac ruins, and visit the intihuatana (pictured below) then you’ll need to go on your own, or get a private tour.
To get to the ruins on your own, go to any of the people offering rides up to the ruins. They hang out or have offices by the bridge over the Urubamba river that you cross when coming from Cusco. A taxi, which can fit up to four passengers, costs s/30. You can also walk from the Pisac Plaza de Armas. It’s a long walk and all uphill but doesn’t take much more than an hour.
