In June of 2015, I went for a 12 day trek in the Peruvian Andes, along the Cordillera Huayhuash circuit, camping 11 nights in freezing temperature, trekking and sleeping above 4100m, hiking up mountain passes 4600m - 5000m high almost every day: all first-time experiences. It was an unforgettable trip, and the mountain scenery along this trek was the most beautiful I have ever seen: snow-covered peaks, glaciers, alpine lakes, lush green meadows, wild flowers... what an amazing place!
