Our guide Carlitos is the best! We had a great and challenging 4 day adventure on the trek with great weather and temperatures from freezing to boiling. I.e. all clothing layers were needed :P. It is amazing how the landscape changes from mountains with glaciers to deep jungle valleys. This was a great experience! There are not enough words to express and explain everything here. Looking forward to seeing Machupichu tomorrow. Muchisimo gracias!!!.
