Introduction

Aragón takes its name from the Río Aragón which runs south from the Pyrenees towards Jaca before veering west to Navarra. The river lent its name to the small Christian county born here in the 8th century AD, and as the county grew into a powerful kingdom it carried the name with it. Today the N330 road runs north up the Valle del Aragón between impressive mountains from Jaca, heading for 1640m-high Puerto de Somport pass on the French border.

Apart from being a route to France's Vallée d'Aspe (with the 8.6km-long Somport tunnel now providing an alternative to the pass), the Valle del Aragón is home to the extraordinary Canfranc train station and the Astún and Candanchú ski resorts, and offers plenty of scenic walks.
