Aínsa

A masterpiece hewn from uneven stone, the beautiful medieval hilltop village of Aínsa is one of Aragón's gems, albeit one that's half-swamped by tourism in high summer. From its perch, you'll have commanding panoramas of the mountains, particularly the great rock bastion of La Peña Montañesa. The modern part of Aínsa, down below, is spread around a busy crossroads and two rivers flowing down from the Pyrenees: the Ara and Cinca.
