The first thing we did that day was to head up past the agricultural terraces to hike to the Sun Gate. The Sun Gate sits in a notch of Machu Picchu mountain and is a tambo and guard post along the Inca Trail.
The path is good and there is little actual climbing so it's a good one for kids, but you still ascend quite a way and it takes a couple of hours one way if you take it easy. It does afford you excellent views of Machu Picchu, Wayna Picchu, the winding bus road and the Urubamba river.
There are quarries along the way and another tambo en route. You'll find yourself walking over the green serpentine rock that is found in the area. Polished pieces of Machu Picchu serpentine are for sale all over Peru.
We spent the afternoon just wandering around the site visiting places we hadn't seen the day before and just generally enjoying the experience.
We lounged for a while on the grassy ceremonial lawn and watched the llamas graze and chase each other.
Next time I'll have a brief post about our last day in Aguas Calientes.
