Must-see in Cusco: a first-timer's guide

New to Cusco? These are the sights locals send visitors to first — enough for a long weekend, and all reachable without a car. 1. Machu Picchu (book far ahead) 2. Sacsayhuamán 3. Plaza de Armas and the cathedral 4. San Pedro Market 5. Rainbow Mountain trek 6. Sacred Valley day trip Tip: go early for the big-ticket sights, and leave one afternoon free to just wander a neighbourhood on foot. That is usually where Cusco sticks with you.
