The Alcalá walk
In Sunrise on the Coast, Sophie regularly walks along a coastal path between Alcalá and Playa de la Arena, and I have strolled this exact same path more times than I can remember (probably because my memory is awful!).
The coastline is rocky and wild in places, and when the surf is up, it can be quite dramatic. It's also a wonderful place to stretch your legs and walk off some of those holiday calories - until you get to the end of your walk and simply can't resist stopping off for some well-earned refreshments.
