A Monterrey adventure group that publishes a full calendar of outings each month, most of them in the Sierra de Santiago and the Cumbres.
Their Matacanes is rated for experienced people — about 19 kilometres with rappels of 30 and 18 metres and more than twenty jumps, adults only, with check-in at the Hotel Cola de Caballo, where the pin sits; they publish no office address. A private date opens from four people. The rest of the calendar covers Hidrofobia, Chipitín, Nido de los Aguiluchos, the Grutas Nevadas, the Ruta Vértigo via ferrata, the Chipinque mesa and peak hikes up Pico Norte, El Chupón and Cerro del Agujerado.
A second number, +52 81 8259 6264, is published for calls.
