The first part of the Camino is somewhat tricky as it is a lengthy journey and Somport is located at 1,600 meters above sea level. The setting is very picturesque, the Pyrenees offer splendid backgrounds.
Some pilgrims decide to walk until Canfranc only. The first part of the day especially is very atypical to the Camino de Santiago as you will find hotels at all times. These do not cater primarily to pilgrims though but to ski lovers. The advantage of passing through tourist sites is that you will find plenty of restaurants and bars at all times.
Jaca is the largest town you will encounter on the Camino Aragones. The Cathedral of San Pedro Apóstol is one of the oldest cathedrals in Spain; its building started around 1070. The citadel of Jaca from the 16th century is also worth a visit.
