After our early morning wake-up, we are still a couple of

hours away from the overlooks.It is pitch black.I can feel the

heavy humid fog left behind my last night's rain. This is why

the tour memo listed "flashlight". Unfortunately; the majority

of our hiking party of nine must have missed the memo, so we

have only four flashlights between us.

An hoar later,we are on the trail. It is dark, foggy, wet and the rocks are alippery.We alternate places between the flashlights "haves" and "have-nots". As we march, the only voices heard are from the "haves": "Step up, step down, watch out for the rock on your left."

We reach Intipunku with only 15 minutes to spare. The view at sunrise is not what we were told in the travel brochures. Three feet in front of our faces is a white substance called "fog".

As we walk towards the Machu Picchu ruins, my anticipation is mounting. When will the fog lift? Slowly, as if someone is cranking up a curtain, Huayna Picchu begins to appear,overlooking Machu Picchu. First there are fleeting glimpses, and then finally, there is, in its full splendor.

When I envisioned going to Machu Picchu, I always thought of mysterious ruins and the famous postcard picture looking toward Huayna Picchu. But there is more to this man-made / natural wonder of the World. It is the adventure of getting there. I knew I wanted to experience the feel of the Inca culture and the energy of this sacred valley, I also knew I didn't want to take the train, but needed to hike. Depending on your starting point,the Inca Trail is 25 to 33miles of semi-arid desert, breathless mountain passes and stunning tropical cloud forest. Our hike took us four nights and 25 miles to finish.

Our local guide MaurO keeps telling us "no worries, the hike is 90 percent mental and only 10 percent physical. "I am not convinced that the physical percentage is correct, but I definitely become more and more excited as we are now getting closer to Machu Picchu.By getting myself into good shape, running 20 miles and hiking a 500-foot-high hill five to seven times per week before I left for Peru, I was able to enjoy the beauty of the hike and not worry much about aching muscles and lungs.
