The Sacred Valley of the Incas, nestled between Cusco and Machu Picchu, is a vital tourist destination offering a rich tapestry of Inca ruins, traditional villages, and stunning landscapes. It is easily accessible from Cusco via organized tours, private taxis, or local buses, though sites like Pisac and Ollantaytambo involve walking on uneven terrain and inclines, limiting accessibility for those with mobility issues. While independent exploration is possible by hiring a taxi for the day or using local transport, guided tours are highly recommended for first-time visitors to gain historical context and manage logistics efficiently, often costing $30-60+ per person (excluding entry fees). The dry season (May-October) offers the best weather for exploring, though the wet season (November-April) presents lush scenery with fewer crowds; comfortable shoes, sun protection, and layers are essential year-round. A full day is typical for a highlights tour, but 1-2 days with an overnight stay allows for deeper exploration and better altitude acclimatization, as the valley sits at a lower elevation than Cusco. Entry to most major sites requires the multi-site "Boleto Turístico del Cusco," costing approximately $35-40 USD for a general ticket.
