Apart from being a more difficult/strenuous day, many trekkers consider this stretch of the circuit the prettiest of the whole loop. We start hiking along the south side of the Carhuacocha Lake before turning south into the Siula Valley where the gradual ascent towards three glacier lakes, Gangrajanca, Siula Cocha and Quesillococha, starts. At Siula Cocha we take a longer break and those participants with some spare energy can climb an additional 30 meter/5 min. towards a ridge from where Grangrajanca Lake can be seen. Especially pretty are the large pieces of glacier ice floating peacefully in the water.
After our break we start the more difficult ascent towards Siula Pass at 4.950 meter - from here maybe the best panoramic view of the Cordillera Huayhuash can be appreciated. After approximately 2 hours downhill hiking towards Lake Quesillococha and Huayhuash Village (4.365 m) we reach our campsite where after a hearty dinner we spentd the night under the stars.
Hiking: 7 - 8 hours - 10 miles
