Would you like to explore the beautiful Cordillera Real in Bolivia and put your mountain climbing skills to test? Then come with us one this Chachacomani and Chearoco program and climb both mountains after a beautiful acclimatization trek around the lakes in the region.

The Cordillera Real is located in the Bolivian Altiplano near La Paz. This gorgeous mountain range boasts several high altitude peaks and many challenging climbing opportunities. On this 11-day adventure, we will head to the top of Chachacomani, at 6074m,  and to the top of Chearoco, at 6127 m. Before tackling these two giants, we will spend the first few days trekking around some of the stunning lagoons in the region.

Chachacomani will be the first of the two mountains that we will climb. It is not technically difficult, but it is physically demanding (PD/III). Chearoco is technically more demanding and for experienced mountaineers. Therefore, it is important to be physically fit and to have the necessary skills to join this program. Of course, we will be there to help and guide you. You can find a detailed itinerary below.

About the guide

guide profile img

Thaki Travel was founded in La Paz, Bolivia in 2011 by Anne BIALEK and Jérôme BENASSI, two adventurous friends, passionate about Bolivia and who fell in love with the kindness of the Bolivians.

During your trip in Bolivia, we will be all the time with you, we personally know all our co-workers from the receptionist of a hotel to a mule-driver of the Cordillera Real.

We like to explore and innovate. Every year, we invest in field expeditions to open new routes and build new original itineraries for our clients. We focus on building strong friendships with local communities giving us privileged contacts and access to off the beaten tracks, like the north part of the Cordillera Real where almost no one else goes.

We are very sensitive to responsible tourism. We have carried out several social actions to improve the lives of local communities and we build all our itineraries in a sustainably-driven approach.
We are very serious about altitude.

All our programs are carefully planned to comply with the acclimatization process, we have trained all our guides to Altitude sickness and we have a partnership with a French Institute about training and research in mountain medicine (Ifremmont). We are the only local travel agency that offers to their clients access to a medical platform (any client having health problems related to altitude can contact a specialized doctor 24/7 through our satellite phones)

We use high quality equipment for our treks and mountain expeditions: North Face VE25 tent (for 2 customers), .., IFMGA mountain guide for 2 customers (English speaking), Oxygen, oximeter, hyperbaric box, satellite phone.
