The massive formed by llampu 6,368m (20,887ft) and Janko Uma 6,427m (21,080ft) is the biggest in Cordillera Real and with no doubt the most majestic of the Bolivian Andes.

According to the Aymara mythology, the mountains are not only the house of the gods (Achachilas) but, they are semi-gods themselves. “Ilapu” was the god of the storms, thunder and rain, and probably that is the origin of the name of Illampu Mountain. Its partner’s name comes from the Aymara words Janko=White and Uma=water.

Starting from Sorata, our trekking route will take us through beautiful land traversing the western slopes of Illampu-Janko Uma massif passing Chillata lagoon on the way to Laguna Glaciar.

Climbers who attempt Janko Uma follow the same route to laguna Glaciar where most of them establish their base camp.

Please note that to take this trip alone, you must already be acclimatized to the highlands. This means that you must have spent at least 3-5 days at the highlands doing light physical activity. Then after having made this trip we strongly suggest booking other mountaineering
