For a few summer evenings each year, around fifty stalls line a 200-metre stretch of Isla Cristina's old town, running from Paseo de las Flores down Calle del Carmen to Paseo de las Palmeras. It's the sort of slow, after-dark wander Spanish towns do well: clothes and handmade decorations, soaps and medicinal herbs, sacks of spices you can smell before you see, and rough-and-ready wooden toys for the kids. Local food fills the gaps between, and there's usually music and a bit of street theatre to slow you down further.
This is a fishing town, so the maritime billing is more about mood than spectacle. Entry is free, and it tends to pull a bigger crowd than an ordinary July night. Easy to fold into an evening of doing very little.
