A Spanish-language agency on Linares, two doors from Gravity, selling the full Cordillera Real list — Charkini, Huayna Potosí, Condoriri, Mururata, Illimani, Chachacomani, Chearoco, Illampu — plus Sajama, Parinacota, Pomarape and Acotango out west, and rock and ice schools for people who want to learn rather than be hauled.
They also run the trekking standards (Takesi, Choro, Yunga Cruz, Apolobamba) and, like every La Paz agency, will sell you Uyuni, Tiwanaku and Copacabana as a sideline.
The website is dated and one of its pages 404s while still showing the contact details. The two mobiles behind the chat widget are live, and the prefilled Spanish messages name the tours.
