The Camino Aragonés climbs from Somport over the Pyrenees before traversing open country in Aragón and Navarra, with exposed tracks, strong sun, cool mornings, and occasional bursts of rain across the seasons. Many start in May, September, and October, when the high pass is typically clear and the plains less hot. Weather remains changeable elsewhere, shade is limited between small towns, and some albergues and services reduce hours or close in colder months.
