We booked a tour to go to Humantay Lake. The tour was booked through our hotel, Ayenda Estancia San Pedro in Cusco for the next morning. It was so amazing that they were able to accept us as TripAdvisor needed two days in advance. Pick up, breakfast, lunch, and a walking stick were included.
The experience was amazing! Everyone in our group were all Spanish speakers and while our group were all very friendly, I genuinely admire our tour guide, Jose for constantly checking in on us. As we were last minute, non Spanish speaking bookers, Jose still took his time alone with us to share with us about the mountains surrounding Humantay Lake, the history of the lake itself, and even tried to get to know us personally.
Luckily horses were available for the trek uphill for 80 soles (about $20 USD). It was definitely a challenge hiking down too, but regardless, it was definitely worth the adventure!
