Zona Zero is an intense trail center in northeastern Spain with 20 challenging, highly-technical routes. Once under the radar, this area has now been discovered thanks to coverage from Specialized and Red Bull, and an impending stop on the Enduro World Series in September 2015. While ranked by some as a "bike park," the trails here are definitely backcountry/enduro-style, and many require GPS tracks in order to navigate them.

Zona Zero is used by some to refer to specific trails near Ainsa, and by others to refer to the entire area. As such, Zona Zero is a bit hard to define, but regardless there is some incredible mountain biking in this region!
