The easiest way to see the following set of Inca ruins just outside Cusco is as part of a half-day tour. The hardy might want to approach it as an athletic archaeological expedition: If you’ve got 15km (9 1/3 miles) of walking and climbing at high altitude in you, it’s a beautiful trek. Otherwise, you can walk to Sacsayhuamán and nearby Q’enko (the climb from the Plaza de Armas is strenuous and takes 30-45 min.), and take a colectivo or taxi to the other sites. Alternatively, you can take a Pisac/Urubamba minibus (leaving from the bus station at Calle Intiqhawarina, off Avenida Tullumayo, or Huáscar 128) and tell the driver you want to get off at Tambomachay, the ruins farthest from Cusco, and work your way back on foot. Some even make the rounds by horseback. You can easily and cheaply contract a horse at Sacsayhuamán, but don’t expect a chance to ride freely in the countryside — you’ll walk rather slowly to all the sites alongside a guide.
