I love my guide. She was so solicitous through the trek. Her skill kept a 74 year old dude safe, having fun, and this was a trip of a lifetime. Best service ever. The food was better than any trek I have traveled. I recommend an increased level for fitness if you think a weekend of walking the golf course will prepare you. I was throughly challenged. The archeological knowledge of the guide and how it was presented made this trip more than a walk in the mountains of Peru, it opened my world to the history of a beautiful people.
