Congosto de Ventamillo, a route between limestone walls
The Ventamillo Gorge or Congosto de Ventamillo closes the access to the Benasque valley from the south. It is a three-kilometre long gorge with impressive vertical limestone walls. It is an ideal route for hiking between the towns of El Run and Seira, and it is possible to start the route in either of them. The route goes around the gorge on both banks at a considerable height and follows a circular route with significant slopes and unbeatable views of the cliffs, the valley of the Ésera and the Maladetas massif.
