One of the most common “bucket list” musts is Machu Picchu, and indeed, the first sight of this city in the sky can surpass even the highest expectations. Peru itineraries also usually include other major Inca ruins such as Ollantaytambo, with terraces rising in spectacular fashion above the Sacred Valley; Pisac, a three-part town with its own magnificent terraces and panoramic views; and Sacsayhuamán, a religious citadel outside Cusco famous for its walls of massive stones fit together with exquisite precision. All these sites are worthwhile.
