is machu picchu worth it?
Yes, it's crowded, but I'd never dare to say one of the New 7 Wonders of the World isn't “worth it”. While there are some brilliant Machu Picchu alternatives, it's safe to say that there's nothing exactly like Machu Picchu anywhere else in the world. The citadel sprawls 325 km2 and there are 172 campuses.
