Machu Picchu. Shrouded by mist and surrounded by lush vegetation and steep escarpments, the sprawling Inca citadel of Machu Picchu lives up to every expectation. In a spectacular location, it’s the most famous archaeological site on the continent, a must for all visitors to Peru. Like the Mona Lisa or the pyramids, it has been seared into our collective consciousness, though nothing can diminish the thrill of being here.
