The region of Sobrarbe is one of the reference places to practice BBT at European level. This area is based in the Zona Zero centre, which signposts, cleans and maintains an ancestral path network in the Ordesa and Monte Perdido National Park. There are routes for all levels.
By our valleys crosses the queen stage of the Pyrenean route in MTB, the track of the Ordesa lookouts, a 2000-metre path that gives us impressive views of the National Park. The Cebollar path is also important. It is a vertiginous descend of one thousand metres by alpine meadows and beech forests with wonderful views toward Ordesa Valley.
