There are local outfitters that start several day hikes to Machu Picchu. The traditional Inca Trail, part of the empire's original network of stone footpaths, has grown so popular that the government caps the number of hikers at 500 a day and requires that all tourists go with a licensed guide. Prices for the four-day trek from operators such as Peru Treks & Adventure start at $295 and include food, entrance fees, porters, and all camping equipment except your backpack and sleeping bag. The dry season (May-September) is best for hiking and exploring, though it's also crowded. Far fewer people come in the wet season, but you run the risk of getting stuck in Aguas Calientes; mudslides sometimes block train tracks for days.
