Stockholm spent the 2010s building a new waterfront on old industrial land at the north edge of Kungsholmen, and against the odds it became the place the city goes to swim in the evening. Hornsbergs Strand is glass blocks, a long promenade, and a set of wooden jetties floating out into Ulvsundasjön — west-facing, which is the whole secret. Three kilometres, best with the sun going down.
Start at Stadshagen and walk downhill to the water. The modern blocks divide opinion; walk them anyway, because the idea behind them — flats to the waterline, jetties open to everyone — turns out to work. Pick up the promenade and follow it south along the lake, past the cafés, to the jetties themselves.
Walk to the end of one and sit. People swim off them, drink on them, watch the light go from them; this is the beat the walk is built around. Then on to Kristinebergs strandpark for the quieter version, and the fika (coffee-and-cake pause) you've earned.
Up to Kristineberg station after sunset. Don't come early.
