This climb is a beast, but worth it. First part is tough, but fine and offers nice views. Then you get some relief for a few hundred meters and see a warning sign with “18%”. This leads to a few hairpin turns that leave you thinking “this is doable”, but then the real deal starts. Long stretches of 15% and up without any recovery. It will test your willpower, but you feel accomplished when reaching the top and the view can’t be beat.

At the entrance roundabout to Castillo Siete Villas , a town in the Cantabrian municipality of Arnuero, this tribute to the pilot and neighbor Salvador Hedilla was inaugurated on July 2, 2016, coinciding with the centenary of the first flight he made from the Peninsula to the Balearic Islands, specifically from Barcelona to Palma de Mallorca. For this flight he used a monoplane designed by him and built under his direction, whose replica made by inmates of El Dueso Prison from a photograph and with materials provided by the city council can be seen in the roundabout. His feat earned him the Mediterranean Cup, a gold trophy donated by the King. https://espanabizarra-tumblr-com.translate.goog/post/166756867086/homenaje-salvador-hedilla-castillo-siete-villas?_x_tr_sl=es&_x_tr_tl=nl&_x_tr_hl=nl&_x_tr_pto=sc
