Saturday nights in Sitges tend to run late, and the quayside at Aiguadolç marina leans right into it. From 11:30pm the bands strike up beside the moored boats, and the whole thing is free, with no ticket and no queue to fret about. The series runs every Saturday through June and July, mixing established acts with tribute shows, so the mood swings from one weekend to the next.

The marina restaurants stay open around it, so you can settle in with a pizza and a cold Estrella before the music starts. It's the sort of warm, unhurried summer evening that locals turn up to as much as visitors. Walk along from the old town, find a spot on the quay, and stay as long as the set holds you.
