Recently, we the opportunity to travel to South America, and one of the highlights was a two day stay in Machu Picchu, Peru. The town of Agua Caliente, at the bottom of the mountain and the end of the rail line, understands the worldwise interest and desire to visit this spectacular site. To see Machu Picchu closeup, you either have to make an arduous climb on foot, or you can take the bus. We recommend the bus trip at the 7000 foot plus altitude, unless you are an afficionado of mountaineering and are in decent physical shape and have the time to burn.
