Ollantaytambo’s namesake archaeological site is one of the best examples of Incan architecture in the region. It’s easy to spend a half day exploring the temples and other structures there, especially if you factor in time to hike up beyond the ruins. Meanwhile, the quaint town itself remains much as it was in Incan times, with original houses, streets, and waterways. Some buildings are open to the public, offering a fascinating glimpse into a centuries-old way of life. Most Machu Picchu–bound trains leave from the station here.
