Hornstullsbastun

Stockholm's first city-run waterfront sauna, on Bergsunds strand at Hornstull, Södermalm. Electrically heated, with room for 16 and a public sun deck over the water.

Book a 90-minute slot online; sessions rotate between women's, men's and mixed. Cool off with a swim in the bay or a cold-water bucket, then warm up again over fika (a coffee break) at Fern & Fika, a few minutes away.
