A trekking outfit in the Calamuchita valley, on Córdoba's provincial register of adventure-tourism providers, running Champaquí, Los Gigantes, the old volcanoes of Pocho, Pueblo Escondido and the waterfalls around, from day walks to multi-day expeditions.
The WhatsApp on their site matches the mobile the register lists. They publish no street address; the pin marks San Ignacio, the village they give as their base.
