Ollantaytambo is a picturesque Inca town that served as both a fortress and a religious center. It is one of the few places where the Incas succeeded in defeating the Spanish conquistadors — a historic moment that makes this site all the more remarkable.
Tip: Ollantaytambo is also the departure point for trains to Machu Picchu. Consider spending a night here to explore the town at a relaxed pace.
