A via ferrata (Italian for “iron road”, plural vie ferrate or in English via ferratas ) is a protected climbing route found in the Alps and certain other locations. The essence of a modern via ferrata is a steel cable which runs along the route and is periodically (every 3–10 m) fixed to the rock. Using a via ferrata kit the climber can secure themselves to the cable, limiting any fall. -Wikipedia
Valencia Adventures hooked me up with a great guide, Juan Carlos, to do the “Ferrata de Dos Aguas” just outside of Valencia. This was a great introductory route to Ferrata. It had enough vertical faces and variation to keep things interesting. The view was fantastic and the cable bridge was a good balance workout. We started late as we’d been peunting all morning so most of our rappel back down was in pitch black. Fun times!
