Creative tour companies will have opened by 2015 a Tarahumara running trip (far-off-road running with the region’s most distinctive indigenous people, the Tarahumara), and biking down the hair-raising but newly paved road to Batopilas, a colonial town hidden in the tropical canyon valleys. The canyons’ rim- straddling adventure park, Parque de Aventura Barrancas del Cobre, is adding a brace of new adrenaline highs too: the world’s longest zip line, and a slingshot ride – which casts you out into the middle of the canyon on a bungee before reeling you squealing back in. Come in, get your canyon fix and get out: far more quickly than ever before.
