Machu Picchu, draped across a mountaintop above dense cloud forest, is deservedly famous. Warm up for its delights by exploring Cuzco's own ruins—Tambomachay, Puka Pukara, Qenko, and Sacsayhuamán—in an easy half day, or visit the Sacred Valley ruins of Ollantaytambo, Tipón, or Písac. In Cuzco, don't miss the Museo Casa Concha which hosts hundreds of artifacts removed from Machu Picchu by discoverer Hiram Bingham and only returned to Peru from Yale University in 2011, a century after discovery. Counter a surfeit of Incan history with a stroll around the labyrinthine alleyways of the San Blas district, or the chaotic San Pedro market, then enjoy a pisco sour from a balcony bar as night falls on the Plaza de Armas.
