The glacis are the grassy, gently sloping bastions surrounding Jaca’s 16th‑century Ciudadela — ideal for wide compositions that include the star-shaped fortress, surrounding town and Pyrenean foothills. Visit at golden hour or blue hour for warm light and long shadows; accessible on foot with nearby parking in town. No entry fee to the glacis; the Citadel itself charges admission if entering the fortress. Weekdays and early mornings reduce crowds.
