29km climb from Laruns but acceptable percentages by bike. The pass in addition to a superb view on the French side is a place of Spanish shops with Ventas and restaurants

Long and steady! 27km of up from the french side upto the spanish border. Save some for the last 10km as it gets a little steeper the higher you climb. And keep an eye out for those cows, especially in the dark - the cowbells help!

The Canfranc Valley has always been a valley of hope. The Somport pass has been one of the most important mountain passes in the Pyrenees since ancient times and these mountains with rugged and steep slopes, shaped by ice, cold and torrents, have seen centuries of stories, trade and communication pass by. And in these times of sports entertainment, self-improvement and active tourism they still continue to save the mythical medieval summus portus, the "highest port", hundreds of pilgrims hoping to faithfully follow the direction of the yellow arrow to the cobbled streets of Santiago of Compostela. La Jacetania has been a border territory in the Aragonese Pyrenees and the people of the valley towns spent their time waiting for the events that passed through the old mountain trails, war roads, grazing, hiding or smuggling, routes dyed with the color of adventure and hope.
