Following the Devil’s Backbone

El Espinazo del Diablo (the Devil’s Backbone—a mountain pass along Mexico’s highway 40) is an infamously sinuous mountain road that joins the towns of Mazatlán, Sinaloa and Durango, Durango. The road has a bit of a reputation for punishing travellers with terrifying accident-inducing winding turns. Luckily travellers are also rewarded with spectacular views as the road runs along a mountain ridge, high in the Sierra Madre mountains. This seemed like exactly the kind of thing we should investigate further.
