A Grade II-listed art-deco lido ('Brixton Beach' to locals) on the edge of Brockwell Park, 50m of open-air water, a sun terrace and a proper café. Heated and open year-round for swimmers, with a gym and spa attached.
Swimming runs in timed sessions you usually need to book ahead, and it gets busy in summer, check the schedule before you turn up with a towel.
The pool charges an entry fee; lounging on the terrace and the café are the free-ish bit. Bring kit if you actually want to get in.
