Once in Peru we booked an amazing tour which consisted in trekking the Colca Canyon.
The guide was fun, the road amazing, and the trek took us two days.
We went to see the Sacred Valley of the Incas and the Ollantaytambo ruins.
We went to Machu Picchu by walk to go to Agua Calientes, and from Agua Calientes to the Machu picchu.
This place is just incredibly hard to get to.
