In the first few days of hiking, we did not seem any other big hiking groups. I only remember seeing two other guys hiking in the opposite direction of ours.
On the second last day of hiking, we hiked only in the morning, reaching a village where we would be resting for afternoon. This was our first chance to bath in the last few days. Two guys and I just jump to the icy cool river to have a quick wash.
Afterward, we just chill out in the village. Then I found out that this village is a major junction on the way to Machu Picchu. Many other groups taking a shorter hike/route to Machu Picchu would be starting their hiking in this village.
The guy second from the right is our local guide. Every night he would be reading a Spanish book by the fire in the kitchen tent. We would be hanging out and getting warm in the dinner tent. These two are the big common tents. We sleep in small two-person tents.
