Plaza Mayor de Cusco, the heart of Cusco, Peru, is a vibrant historical square surrounded by stunning colonial architecture and the imposing Cusco Cathedral. Accessibility is generally good, but the altitude can be a factor for some visitors, so acclimatization is essential. Exploring solo is feasible and enjoyable, allowing you to soak in the atmosphere at your own pace, but guided tours provide deeper insights into the plaza's rich history and significance. There are no seasonal restrictions, but the dry season (May to September) offers the best weather. Expect to spend approximately 1-3 hours here, and costs are minimal, primarily for entrance fees to the cathedral or any museums located on the plaza. Be aware of potential scams targeting tourists.
